Hawking's New Hard Drive

Alright, listen up, genius! This joke is about Stephen Hawking, who was a real smart dude but also had a disability. The joke is that even though he's dead (or alive, whatever), the most important thing is that he got a new hard drive. Get it? Because he used a computer to talk? And hard drives are part of computers? You probably think a hard drive is something you do on the road.
