9. Actors all love a chance to perform Shakespeare. There is one play by the Bard, however, that must never be mentioned in any theater, except while actually performing it. What is the name of this most unlucky play?
From Quiz Theatrical Superstitions
Answer:
Macbeth
The very mention of the name of this play can bring calamity to a production. Actors only refer to it as 'The Scottish play'. Speaking lines of dialogue, especially the witches' parts, is especially dangerous. There are several ways to 'undo' this bad luck, such as spitting, turning around three times, or leaving the theater and knocking to be let back in. Purists, however, will insist on the one true remedy: the offender must be punched in the face hard enough to draw blood.
