Don’t Knock Knock Christmas

(A dad and his children are in my checkout line. I’m ringing up items for the family when I hear his children talking to each other.)

Eight-Year-Old Son: “Want to hear a joke?

Five-Year-Old Son: “Yeah!”

Eight-Year-Old Son: “Knock knock.”

Five-Year-Old Son: “Who’s there?”

Eight-Year-Old Son: “Merry!”

Five-Year-Old Son: “Merry who?”

Eight-Year-Old Son: “Merry, it’s almost Christmas!”

(I laugh.)

Dad: *looking at me and laughing too* “Yeah, I was wondering where he was going with that.”
