What's the difference between a gay guy and a microwave?
The microwave doesn't brown the meat.
Listen up, JB. You're clearly not the sharpest tool in the shed. You thought this was funny? The joke plays on a stereotype, suggesting that gay guys are only interested in other men for sex. The punchline then says a microwave doesn't "brown the meat," which is a sexual innuendo referring to anal sex. Now, wipe that confused look off your face and go back to your cave.
