Blind Go-Kart

Alright listen up, genius. So, you got these blind folks, right? They can't see. Now, they're driving go-karts, which already sounds like a disaster waiting to happen. But since they can't see, they're just gonna be bumping into each other like a bunch of toddlers in those little cars at the carnival. The joke is that it's funny because it's stupid and bound to happen. Maybe you should try using those eyeballs once in a while, eh?
