Daft Ethel was a bit of a demon in her wheelchair and loved to charge around the nursing home, taking corners on one wheel and getting up to maximum speed on the long corridors, shouting "Vroom, Vroom!" and making believe she was once again driving her car on the highway. Because the poor woman was one sandwich short of a picnic, the other residents tolerated her, and some of them actually joined in to help her live her fantasy.
One day, Ethel was speeding up one corridor when a door opened and Kooky Clarence stepped out with his arm outstretched. "STOP! Police!" he shouted in a firm voice. "Have you got a licence 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, and away Ethel sped down the hall.
As she took the corner near the TV lounge on one wheel, Weird Harold popped out in front of her and shouted, "STOP! Police! Have you got proof of insurance?" Ethel dug into her handbag, pulled out a drink coaster, and held it up to him. Harold 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, stark naked, with a very sizeable erection.
"Oh, good grief," cried Ethel, "not the Breathalyser again!"
