Interrupting Cow

Listen up, buttercup. This joke is all about an interrupting cow, see? It's a play on words, like when your mom tries to be hip. The setup is a classic "knock knock" joke. The punchline? Instead of saying who, the cow just yells "moo" and cuts you off. It's funny because cows don't talk, and you are expecting the cow to answer the question, but all you get is "Mooooo!" You are so dumb, you probably ask cows what they eat. You can't fix stupid. Sad.
