There was this guy who was married to a blonde, and each night he came home with a new blonde joke. One night the wife got mad and decided¹ to show him that she wasn't dumb. She spent the whole next day learning all her states and capitals.

That night when he got home he told his joke. She says, "I'm not so dumb. I know all of the states and capitals. Go ahead, quiz me."

He thought for a moment and asked, "What is the capital of Massachusetts?"

She quickly replied, "M"!
