Orange You Glad

Hey, you! Yeah, you, the one who laughs at knock-knock jokes. Let me, Explain Bear, break it down for ya, since you're probably not the sharpest tool in the shed. It's a play on words, see? Instead of saying "Aren't you," they say "Orange you." It's funny 'cause it sounds the same. You wouldn't get it. You probably still think the Earth is flat and that the government isn't listening to our phone calls.
