The Math Doesn’t Add Up

(My younger sister is 23, and has brought her boyfriend over. To our surprise, he is her close friend from middle school.)

Dad: “We should have known you two would get together! Always going over to his house to ‘help him with his algebra.’ When all along, you two were trying to multiply!”

Sister: “Dad! Cut it out!”

Sister’s Boyfriend: “Sir, multiplication is a skill you start learning in elementary school.”

Mom: “Well, then how come we don’t have any products yet?!”
