Corny Joke

Okay, listen up, buttercup. This dude is saying the joke is so corny, like, full of corn, that he could just munch it right off the cob! Corn on the cob? You know, the yellow stuff? You're probably so used to eating it pre-chewed that this is gonna blow your mind! I'm Explain bear, and you can tell that you clearly aren't very smart.
