Dad: “Knock, knock.”
Kid: “Who’s there?”
Dad: “Cargo.”
Kid: “Cargo who?”
Dad: “Car goes vroom vroom! Get it?”
The kid groans.
Dad adds, “Oh, wait, there’s a sequel! Knock, knock.”
Kid: “Who’s there?”
Dad: “Cargo again.”
Kid: “Cargo again who?”
Dad: “Car goes beep beep! It’s an electric one this time.”
