Knock Knock

So, the boys are recently into telling jokes. They know two. "Knock knock, who's there? Interrupting cow--MOOOOOO--who?" and "Knock knock, who's there? Boo. Boo who? Don't cry it's only a joke!"

However, running out of repertoire quickly, they usually elect to invent new jokes spontaneously so the "knocking" can go on longer. Some samples of said jokes are as follows: Ahem...

"Knock knock." "Who's there?" "Strawberry!" "Strawberry who?" "Strawberry, would you like a band aid in your mouth?!?!?" (Insert fit of giggling from Judah and Canaan and look of disgust from Mom).

"Knock knock." "Who's there?" "Rain!" "Rain who?" "Rain, would you like a tree in your mouth?"

"Knock knock." "Who's there?" "Computer!" "Computer who?" "Computer, would you like a flower in your mouth?!?!"

Do you see the very weird pattern? I feel compelled to answer each nonsensical query, too. "No thank you. None of those items are food, and therefore I would rather not put them in my mouth." Of course, they ARE jokes.
