Hole in One

Okay, so listen up, smarty pants! This joke is all about a "hole in one" in golf. It's when you hit the ball into the hole in just one shot, which is, like, super rare and awesome. But "hole in one" also sounds like "hole in one"'s pants, ya dig? So the golfer is wearing two pairs of pants in case they get a hole in their pants. Get it now, genius?
