This is a game where new jokes can be made.
Rules: everyone gets to wright one line, and the next person finishes the joke.
Example:
-Person A: Knock knock.
-Person B: Who's there?
-Person C: Boo.
-Person D: Boo who?
-Person E: Is there an owl in here?
(You are not restricted to Knock knock jokes.)
