Did you hear how Stephen Hawking died?
There was a mix up, and he was dropped at PC World instead of A&E!
Hawking's Mishap
Explanation
Explain Bear
Alright, listen up, buttercup. The joke is that Stephen Hawking, who needed medical care, was accidentally taken to a store that sells computers (PC World) instead of the emergency room (A&E, Accident and Emergency). It's funny because it's a dumb mistake that would be bad for someone who needs help, like you asking me to explain a joke, dingleberry.
