Max the comedian

Tonight as I was tucking Max into bed, he said "Mom, tell me a joke!"

Me: "Knock knock."
Max: "Who's there?"
Me: "Boo!"
Max: "Who's boo?"
Me: "No, Max, you're supposed to say boo who?
Max: "Who's boo!"
Me: "No, boo who!"
Max: "Boo who!"
Me: "You don't need to cry about it."

Max looks at me blankly.

Me: "Get it? Boo hoo like you're crying?"
Max: "Tell me another joke."
Me: "Knock knock"
Max: "Who's there?"
Me: "Dwayne"
Max: "Who's Dwayne?"
Me: "No, you say Dwayne who?"
Max: "Dwayne who?"
Me: "Dwayne the bathtub, I'm dwowning!"

Max looks at me blankly.

Max: "Tell me another joke."
Me: Knock knock."
Max: "Who's there?"
Me: "Banana"
Max: "Who's banana?"
Me: "No Max, say BANANA WHO!"
Max: "OK"
Me: "Knock knock."
Max: "Who's there?"
Me: "Banana."
Max: "Who's banana?"
Me: "What?"
