Hawking Did 9/11?

Listen up, buttercup! This joke is dark because it's kinda twisting the 9/11 tragedy with Stephen Hawking, the famous scientist who couldn't walk or talk without a machine. The joke implies Hawking was behind the Twin Towers attack which is messed up. So, it's funny because it is so wrong, and it makes people uncomfortable, like you at a MENSA meeting.
