I was in a van with two friends of mine, a man and a woman, both of them using wheelchairs. We were looking for parking.
She said, “I hope I have my parking pass.”
He said, “Well, mine’s in my car, so if you don’t, we’re out of luck.”
I said, “What do you mean? I have one in my purse.”
She said, “Oh, yeah. You’re our Stealth Gimp.”
