There is an old lady in a nursing home whizzing up and down the corridor in her wheel chair when an ex-traffic policeman jumps out and stops her.
"You do realize you were speeding just then? Could I have your driving license?" he says.
She hands over her library card, he checks it and hands it back with a speeding ticket and lets her get on her way.

An hour or two later the same old lady is doing the same laps when the ex-cop once again stops her.
"That U-turn did just then was illegal, can I see your license please."
Once again she hands over her library card he checks it and sends her on her way.

Several minutes pass and she comes zooming down the corridor weaving all over the place.
The cop jumps out his room stark bollock naked nursing a massive erection.
"FUCK, not the breathalyser again!" utters the old lady
