Hospital or PC World?

Okay, listen up, buttercup. Stephen Hawking used a wheelchair and a computer to communicate because he had a disease that made it hard to move and speak. So, the joke is asking if you should take him to a hospital because he's sick, or to PC World (a British tech shop) because he needs computer help. You probably think PC World sells computers, right? Ding, ding, ding! You are so smrt!
