Man, I’m so sorry that Stephen Hawking is dead; he was such a good person.
Too bad it’s a staircase to Heaven and not a ramp.
Staircase to Heaven
Explanation
Explain Bear
Listen up, buttercup. This joke is about Stephen Hawking, a smart dude who used a wheelchair. The joke is funny because it says Heaven should have a ramp instead of stairs so Hawking could roll right in. It's kinda dark, but also points out the obvious!
HEHA
He went to hell
Ye nan
He will probably teleport up there in these "black holes"
