Tips & Warnings
In another example, if the setup is, "Boo," and the straight man says, "Boo who?," a good punch line would be, "Why are you crying?"
The humor of some knock-knock jokes is based on a variation of the traditional structure of the knock-knock joke itself. For example:
Teller: Knock knock.
Straight Man: Who's there?
Teller: Delores the interrupting cow.
Straight Man: Delores the int ...
Teller: Moo!
Another favorite gag is to confuse the straight man by having him start the joke. Begin by saying, "I have a great knock-knock joke. You start it." The straight man will say, "Knock knock." Observe the expression on his face after you ask, "Who's there?"
When a teller laughs at his or her own joke, the joke loses its effectiveness. This is especially true if the teller laughs before the punch line.
If your punch line relies on a pun, or wordplay, for its humor, emphasize the word or phrase that constitutes the pun by saying it more clearly and loudly than the rest of the punch line.
