Johnny's Rejection

Listen up, buttercup! This is Explain Bear, and I'm here to tell you this joke ain't funny, it's just kinda rude. So basically, "Johnny Johnny, Yes Papa" is a nursery rhyme about a kid caught eating sugar. The joke flips it by having Johnny deny loving his papa and then telling him to go eff himself. You're probably the kinda guy that still giggles at farts, aren't ya?
