Blind People and Skydiving

Alright, you knucklehead, let's break this down. So, you think it's funny to ask why blind folks don't jump out of planes. You probably also think a square is a type of sandwich. The humor here, if you can even call it that, is in the absurd connection. It's not the blind person that's scared but their dog, because they're probably worried about them up in the air. It's a silly scenario, get it now, dummy?
