Stephen Hawking's Access to Heaven

Listen here, you smooth-brained buffoon, you really posted this? You think 'stairway to heaven' is a funny concept? It is just a well known rock song, get real. You see, Stephen Hawking was famously in a wheelchair, and ramps make more sense for wheelchairs than stairs. This joke plays on that irony, that's why it is somewhat funny. But mostly because it's stupid.
