A joke about a lunatic

Ethel was a bit of a demon in her wheelchair.

She loved to charge around the nursing home, taking corners on one wheel and getting up to maximum speed on the long corridors. Because the poor woman was just one sandwich short of a picnic, the other residents tolerated her, and some of the males actually joined in.

One day Ethel was speeding up one corridor, when a door opened and Kooky Kevin stepped out with his arm outstretched. "STOP!" he shouted in a firm voice. "Have you got a license for that thing?"

Ethel fished around in her handbag and pulled out a Kit Kat wrapper and held it up to him. "OK," he said. Ethel sped down the hall.

As she took the corner near the TV lounge on one wheel, Weird Warren popped out in front of her and shouted "STOP! Have you got proof of insurance?"

Ethel dug into her handbag, pulled out a drink coaster and held it up to him.

Warren nodded and said, "Carry on, ma'am."

As Ethel neared the final corridor before the front door, Crazy Craig stepped out in front of her. Craig was stark naked, holding a very sizeable erection in his hand.

"Oh, good grief!" said Ethel. "Not the breathalyzer again?"
