Ha! When I worked at a factory, a couple of people were fanatics about picking up pop cans for the deposit. One time "Sally" (an older lady) picked up some pop cans that were promised to "Gerald" (older coot). He got mad and super glued her combo lock shut. They had to get the bolt cutters. Gerald got a write up.
If your takin' your girlfriend out tonight
You better park the car well out of sight
'Cos if they catch you in the back seat trying to pick her locks
They're gonna send you back to mother in a cardboard box !
