Mixed Pouch of Snuff Trivia Quiz

Answer: Water, generally speaking

In the goblin religion of Unggue everything that was at one time part of the goblin's body (like snot, earwax and nail clippings) should be treated with highest reverence - and should therefore be stored in handcrafted Unggue pots. Pastor Mightily Oats teaches us that 'water, generally speaking, is not reckoned as Unggue. It is merely going through the body without ever being part of it.'
Er... Kids, do NOT try this at home.

Answer: Avec

Wow-Wow Sauce is a favourite condiment of Mustrum Ridcully, UU.
Sheep's Eyeballs is one of the rather hilarious foods served in Klatch.
The Meat-pie floater can be found in Fourecks, as Rincewind could tell you at the speed of beer.
'Avec' is generally (over-) used in Quirmian food, much to the distress of many of Ankh-Morpork's citizens.

Answer: Hang!

Yes, the goblin variant of 'hi' is 'hang!'. Sounds weird, but, after all, there's only a limited number of syllables in the world, right?

Answer: The Poo Lady

Sam Vimes calls her the Poo Lady because apparently most of Miss Beedle's books revolve around poo like flies around ... well, around poo.
Some examples of her great literary works include 'The World of Poo' and 'Geoffrey and the Land of Poo'. Great reading!

Answer: The Marquis of Fantailer

The Marquis of Fantailer's rules for fisticuffing state, for example, that you should treat your opponent with respect and fairness. Consequently, you are not allowed 'to put your boot in' once the other bugger's down.
Sam Vimes is, understandably, no friend of the Marquis' way of fighting. He knows that many a dying man's last words were 'Damn that Marquis of FantARGH!'

Answer: One Man He Up Down Very Sorry

When constable Upshot tries to arrest Vimes because of his possible involvement in the disappearance of the blacksmith Jefferson, Vimes tricks Upshot into giving him his official truncheon. Vimes, in the face of the young, unarmed police officer feels quite safe now. What he doesn't know is that Feeney's granny, Ming Chang, came from Bhangbhangduc. Subsequently she taught the family two important domestic skills: cooking and fighting.

Answer: The Summoning Dark

The Summoning Dark is assumed to be quasi-demonic entity which has gained access to Vimes' mind. Despite being millions of years old, it isn't able to lure him into darkness. Vimes has, in his mind, created the Guarding Dark as a counterpart to the Summoning Dark. This allows him to draw on the power of darkness unharmed.
(Please read 'Thud!' for more detailed information on the concept of living, and possibly breeding, darkness.)

Answer: The Wonderful Fanny

Sam Vimes reasons that probably the owner's wife was called Franceska. This, being rather a mouthful, led to the abbreviated Fanny.
En al Sams la laisa, for those who care, is translated as 'the place where the sun shineth not (please take a look at Sir Pratchett's 'Jingo' for more context).

Answer: Mr Murderer

Although the Murderers are a very respected family in the Quirm area, the recent involvement of captain Murderer in the abduction of the blacksmith Jethro Jefferson and the smuggling of dangerous troll drugs will in all probability lead to legal defficulties in the near future.

Answer: A steel comb

The steel comb, as we now know, can be quite lethal when wielded by Mr Willikins. As we also know, the description 'gentleman's gentleman' contains two lies when applied to Mr Vimes and Mr Willikins.
By the way, I assume that the Soul-Eater might also be deadly in Willikins hands. But I'm not sure if it can actally be called your common household item.
