Rhy Rhy Rhyde

Alright listen up, chucklehead. This joke is what we call a "yo mama" joke but instead of yo mama it's deez nuts. The joke asks if you know a Pokemon called "rhy rhy rhyde," which sounds like "ride." The punchline is "deez nuts," implying you're being asked if you want to ride deez nuts. You probably still wear a helmet when you aren't riding anything.
