Why did Stephen Hawking die?
Because there was a power cut.
Alright, listen up, you chucklehead. Stephen Hawking, right, he was a smarty-pants scientist who needed electricity to run his talking computer. So, get this: he "died" because of a power cut. It's funny because, without power, his special computer couldn't keep him going, get it? And, by the way, you are so dumb that you still use Internet Explorer.
