Stand-Up Comedy

Okay, so you know that Stephen Hawking was a super smart dude who, sadly, couldn't move so good because of a disease? The joke is that he can't do "stand-up" comedy because, well, he can't stand up! Get it? It's funny because it's literally impossible for him. And, based on your joke skills, you're probably as mobile as the great man himself. Sad, isn't it?
