The Milk Run

Listen up, buttercup. So, this joke is about a dude whose dad went out to buy milk. But here's the kicker: they have a cow at home! Cows make milk, genius. The joke is that the dad is dumb because he doesn't realize they can just milk their own cow. It's like you trying to solve a math problem without using your calculator, which you probably do all the time, you silly goose.
