He Who Must Not Be Seen Trivia Quiz

Answer: Cheers

Arguably the bar's most loyal customer, Norm occupies the same corner bar stool at Cheers each night, downing beer after beer and cracking jokes, which are usually at the expense of his wife, Vera. The long-standing running gag is that although Vera's voice is heard from time to time, the audience never gets a proper look at her, even after she gets a job working at the restaurant above the bar.

Her legs are briefly shown in one episode, and in another her arm can be seen waving to Norm from a passing car to mark their wedding anniversary.

In the season five Thanksgiving episode, Vera finally enters the bar but gets a pie thrown in her face by Diane. Norm spends most of his waking hours at the bar, ostensibly to avoid his wife, although it is obvious that he truly loves her.

Whenever we hear Vera off-screen on the show she was voiced by Bernadette Birkett, who was married in real life to George Wendt, the actor who played Norm.

Answer: A microcassette recorder

Dale Cooper, the unconventional FBI Agent at the center of the cult-favorite "Twin Peaks", has his share of quirks and oddities. He employs investigative methods inspired by Tibetan mythology, and can never say no to washing down a slice of cherry pie with a "damn fine cup of coffee". Perhaps his strangest habit is his practice of using his trusty microcassette recorder to document his thoughts on his cases, as well as observations about life in general. All of his recordings are addressed to someone named "Diane", but she is never seen or heard throughout the show's first two seasons.

The only indication that anyone is even listening to the tapes is when Coop receives the earplugs he asks for in one episode. (In the film "Twin Peaks: Fire Walk With Me", Agent Cooper has a conversation with an unseen "Diane" when he visits the office, so it seems clear that she works for the Bureau.) In 1990, the audiobook "Diane...

The Twin Peaks Tapes of Agent Cooper" was released and earned actor Kyle MacLachlan a Grammy nomination for Best Spoken Word Performance.

Answer: Morbid obesity

For some reason, fat jokes seem to be a perennial favorite with sitcom writers. All of these supporting characters were never (fully) portrayed on these shows, possibly because nothing could live up to whatever the audience was imagining. Peggy's mother in "Married... with Children" is described as being incredibly obese but is never shown, even after she moves in with the Bundys in season ten. Al's mom on "Home Improvement" is never seen, but after she dies her coffin provides an idea of her size - it is humongous and requires 17 pallbearers. Karen's husband, Stan, on "Will and Grace" is also never entirely shown, but is described as being fat and single-handedly responsible for keeping Pizza Hut and Taco Bell in business. Mrs. Wolowitz on "The Big Bang Theory" is also never completely shown, although the show did once tease audiences by showing her massive frame walking repeatedly past a small opening in her kitchen door while she prepared her famous brisket for Raj in "The Spoiler Alert Segmentation".

The audience usually only heard the distinctive voice of actress Carol Ann Susi, who portrayed the character until her death in late 2014.

Answer: Charlie's Angels

Charles Townsend lent his name to the detective agency and television drama that ran for five seasons from 1976 to 1981, but was curiously absent for most of the show's run despite being named in its title. Audiences only ever heard Charlie talking to his employees through a desktop Western Electric model speakerphone.

Instead, the show focused more on the exploits of his beautiful (and equally capable) women investigators, and made household names of Kate Jackson, Farrah Fawcett, Jaclyn Smith, and Cheryl Ladd. Charlie himself was voiced for the show's duration by John Forsythe, who also provided the voice for Charlie in the two film reboots of the TV series released in 2000 and 2003. Forsythe only appeared in front of the camera in the final episode of the TV series, "Let Our Angel Live", which sees Kelly Garrett (played by Jaclyn Smith) requiring surgery after being shot, while the rest of the team reminisce about her exploits in previous cases.

She comes to at the end of the episode to find Charlie sitting by her bedside.

Answer: Maris

Maris was the butt of many jokes on "Frasier", which usually played up the bizarre physical characteristics and personality of this often-mentioned but never-seen individual. Her role was never cast because the show built up such an otherworldly collection of attributes that no actress alive would have been able to match the mental image that the audience had of the character.

She was dangerously anorexic for most of the show, domineering, conceited, and highly neurotic. She was deathly allergic to a host of everyday objects, had webbed hands, and could not produce saliva. Once, she was mistaken by Roz for a hat rack, and was able to sit on a whoopee cushion without setting it off. And as Frasier once observed, "Maris is like the sun, except without the warmth." She eventually divorced Niles and ended up fleeing to a private island to escape prosecution for the alleged murder of her Argentinian lover.

She was only portrayed onscreen on rare occasions. Her silhouette was shown once through a shower curtain, and Niles visited her in hospital when she was covered from head to toe in bandages.

Answer: South Park

Kenny McCormick is one of the elementary school protagonists of "South Park", the Comedy Central sitcom created by Trey Parker and Matt Stone that famously skewers everyone and everything. Kenny is probably just as foul-mouthed as Stan, Kyle and Eric, his compatriots in the fictional town of South Park, Colorado, but it's hard to tell as everything he says is usually muffled by the hood of his bright orange parka, which covers his entire head leaving only his two eyes bulging out of the opening. His entire face has only been shown a handful of times, starting from the 1999 "South Park" movie, and since then in a few episodes of the TV show.

The show's first five seasons also featured a running gag in which Kenny is killed in almost every episode, usually in a gory and over-the-top manner. Kenny remained dead after the fifth season and was therefore absent for most of the sixth season, until his sudden and unexplained return in the season six finale. Since then, he has remained one of the core characters of the show, and is only ever killed off occasionally.

Answer: Gossip Girl

"Gossip Girl" ran for six seasons between 2007 and 2012 and revolved around the social lives of a privileged group of prep-schoolers in New York's Upper East Side. Each episode is narrated by the mysterious Gossip Girl (memorably voiced by Kristen Bell throughout the show), the chronicler of every scandal, rumor or revelation concerning the students of Manhattan's prestigious Constance Billard and St. Jude's schools.

There's Blair Waldorf, queen bee and best friend to Serena van der Woodsen, her generation's "It girl", Nate Archibald, Serena's male counterpart, and the incorrigible, womanizing Chuck Bass.

The lives of all of these characters are impacted in some way by the titular blogger, whose true identity is eventually revealed in the show's final episode to be outsider Dan Humphrey, who only created the persona so that he could break into the exclusive clique of teenagers and win Serena's love.

Answer: A backyard fence

It wouldn't be an episode of "Home Improvement" without the familiar sound of Wilson saying, "Well hidey-ho good neighbor!" Portrayed by Earl Hindman for eight seasons of the show, Wilson was the wise and friendly widower living next door to the Taylors who was always ready to wax philosophical on everything from Herodotus to Shakespeare to ancient Celtic proverbs to help his neighbors' woes.

A lot of the show's humor came from watching Tim butcher Wilson's many parables, to the confusion of the rest of his family. Because their interactions with Wilson usually occurred in their backyard, only the upper portion of his face could be seen peering over the top of their backyard fence. Over time, the show expanded this running gag by using other objects to obscure part of Wilson's face when he wasn't standing by that fence, like a scarf, a fake beard, a plant, a yam - whatever was handy. Earl Hindman even held up a miniature white picket fence whenever he appeared in the cast's curtain call at the end of taping each episode.

His full face was finally shown to the studio audience during the curtain call for the final episode of the series.

Answer: How I Met Your Mother

The premise of "How I Met Your Mother" is an interesting one. The year is 2030, and Ted Mosby is telling his two children the story of how he met their mother. Most of the events portrayed on the show unfold as a series of flashbacks depicting the life of twenty-something Ted and his friends in New York, chronicling Ted's numerous failed relationships leading up to the momentous meeting with the future mother of his children. Until the end of the eighth season, details of "The Mother" (as she came to be known for most of the series) were kept under an impenetrable shroud of secrecy - her voice was never heard, her face was never shown, and she was only ever portrayed in passing as a mysterious woman holding a yellow umbrella.

It was only in the season eight finale that the Mother was finally depicted on screen and portrayed by Cristin Milioti, who joined the series cast for the show's ninth and final season, and it wasn't until the series finale that her name was finally revealed.

Answer: Ugly Naked Guy

In "The One with the Flashback", we learn that he used to be known as "Cute Naked Guy" but eventually became "Ugly Naked Guy" after he put on a lot of weight. It's a good thing that he was evidently an exhibitionist, as everything he did in his apartment could be seen very clearly from Monica and Rachel's place across the street. We know that he wears gravity boots, plays the cello, has a habit of burning himself with candle wax, and likes to partake in "ugly naked dancing" with his Thanksgiving dinner guests. We see his naked belly when the gang assembles a "Giant Poking Device" out of chopsticks to determine if he had succumbed to Phoebe's dentist-related curse.

He is also shown from behind when Ross partakes in some ugly naked bonding with him over muffins so that he can sublet his apartment.

When Ugly Naked Guy eventually moves out, Ross observes, "Ironically, most of the boxes seem to be labeled clothes."
