Boy #1: Knock, Knock
Boy #2: Who’s there?
Boy#1: Insert pretty much anything here, really, pretty much anything goes. For clarifications purposes we will refer to this as the joke subject.
Boy #2: You know how this goes right? [Joke subject] who?
Boy#1: [Joke subject] in their/his/her underwear!
Tilt face up to the sky, laugh as if you just heard the most hilarious thing ever, and repeat with new joke subject (or continue to use the same joke subject because that is funny too.) Apparently for a six and four year old boy, this type of joke format is something that can be (and is) repeated over and over again for hours on end and into days and weeks and is never found to be old.
Some of their favorite joke subjects are Momma, Poppa, Dexter, Delilah, and squirrel. I fear this is going to be one long summer vacation.
What are your favorite joke subjects?
