Cow Crossing

Listen up, buttercup. This joke is udderly hilarious because it's a pun! You see, "utter" sounds like "other." So the cow wants to get to the OTHER side, but the joke implies the "utter" side. Get it? It's punny 'cause cows have utters. You probably don't know what an utter is. It's where milk comes from, you city slicker.
