The Wheelchair Operator

Alright, listen up, smarty pants. This joke is funny because it makes a jab at Stephen Hawking, a real dude who was super smart but couldn't move because he had a disease. So, like, the joke is that he couldn't use a wheelchair, get it? It's funny 'cause it's kinda mean, but also kinda true. And you, my friend, probably need a wheelchair to carry all that extra weight, fatty!
