A Michael Jackson knock-knock joke I would only perform this joke if A) You've seen the South Park episode with MJ and B) You don't mind hitting a high note in front of a crowd. This isn't your typical joke because the punchline relies on the delivery of the person you are telling the joke to. If done right, it's hilarious--just have faith in me, I've tried it plenty of times. ========= First say ""Hey, I've got a Michael Jackson joke for you."" (it will help them get the ""punchline"" because otherwise they will be confused.) Then begin: Knock knock Who's there? *Ah-hoo!...* ***here you have to sound like MJ in the SP episode.** Now this is where the humor is--if they are a good sport they will respond back in the high pitch asking, ""Ah-hoo-who?"" and it will sound just like one of those random blurbs MJ sings between lines in a song, or especially, how he sounds on the South Park episode. The person you are telling the joke to will laugh afterwards realizing how they just sounded like MJ. If they respond poorly (eg just repeats the ""Ah-hoo"" part in a deep voice) then just smile and laugh it off and show them how its done. Good luck!
