Hawking at the ATM

Alright, listen up, buttercup. The joke is that Stephen Hawking, who was a brilliant scientist but also used a machine to speak, was seen using an ATM. The funny part is the punchline, "before he shut down," which is a play on words. It refers to both Hawking's eventual death and the fact that machines shut down. Get it? It's like, HA HA, cause the dude DIED!
