Hawking vs Refrigerator

Alright listen up, you chucklehead. The joke is that Stephen Hawking, even though he's smart, can't move because he got that ALS thing going on. But a fridge? It "runs", as in, it works and moves. Get it? I know you didn't, you sound like the kinda dude who thinks mayonnaise is a musical instrument.
