"Knock, Knock"

It's not yet 7am. I am sitting at the computer: books for the day--check; power-tie--check; cup of coffee--check; knock-knock jokes--che...what? The girls are in the living room playing in their princess castle. I overhear Pita saying, "Knock, knock. Who's there?" Madge replies, "No, Peach. You just do the first part." She catches on after a try or two. The following jokes are the big hits (don't ask me why):

Knock, knock. Who's there? Banana strawberry. Banana strawberry who. Banana strawberry princess. Teeheehee.

Knock, knock. Who's there? Strawberry. Strawberry who. Strawberry mommy. Teeheehee.

Thanks for the morning entertainment, my beautiful girls.
