Ethel is a bit of a demon in her wheelchair and loves to charge
Around the nursing home, taking corners on one wheel and getting up to a
Maximum speed on the long corridors. Because the poor dear is several
sandwiches short of a picnic, the other residents tolerate her eccentric
behavior, and some of them even join  in the fun. One day Ethel is
speeding along one of the corridors when a man steps out of one of the doorways
with his arm outstretched:  
"Stop!" he says firmly,"have you got a license for that thing?".
Ethel fishes around in her handbag and pulls out a Kit-Kat wrapper,
which she hands to him with a big smile.  "OK" he says, and off she
goes again. Taking the corner by the TV lounge on one wheel as usual,
she finds another man standing in the corridor in front of her.  "Stop!
Have you got a valid registration for that vehicle, madam?" Ethel digs into her
handbag again and comes up with a gum wrapper Which she presents for inspection,
whereupon she is sent on her way once  more. Heading down the last
corridor before the front door, a third man steps out in front of her.  He is
stark naked, and holding a sizable erection in one hand.
"Oh no", cries Ethel, "Not the breathalyzer again!!!"
