Inaccessibility jokes

I can't stand being in a wheelchair.

I used to get pushed and called lazy in school.

Man, I loved that wheelchair.

Have you ever walked into Stephen Hawking's house? No, he hasn't either.

I lost a race with a handicapped person today. The problem was the race was all stairs.

Gravity sure is fast.

I should be ashamed of myself for making all these jokes at the expense of the disabled! After all, they can't even stand up for themselves.
