"Speeding in the wheelchair" joke

An old lady in a nursing home is speeding up and down the hall in a wheelchair, making noises like she is driving a car.

As she is going down the hall, and old man jumps out of his room and says. "Excuse me ma'am, you are speeding. Can I see your drivers license?"

She digs around in her pocketbook and pulls out a candy wrapper. He looks it over, gives her a warning and sends her on her way.

Up and down the hall she speeds again. The same man jumps out of his rooms and says, "Excuse me ma'am, but you crossed over the white line. Can I see your registration?" She digs through her pocketbook again and she pulls out an old receipt and hands it to him. He looks it over, gives her a warning and sends her on her way.

She zooms off. Up and down the hall, weaving in and out. This time, the same man jumps out of his room. He is stark naked and has an erection!

The old lady in the wheelchair looked up at him and said, "Oh no, not the Breathalyzer again!"
