Hawking's Screw

Alright, listen up, buttercup. So, Stephen Hawking, right? Dude was a genius but also needed a wheelchair to get around. The joke is that a "screw fell out", get it? Like, a screw from his wheelchair, which caused him to die. It's dark, kinda stupid, and definitely not gonna win any comedy awards, just like you're not gonna win any awards for being smart!
