THE BIKER GANG
A biker gang comes into a transport cafe
and start picking on a little middle-aged man just sitting down to an all-day breakfast. They steal most of it, spit in his tea, and pull away his chair from under him, until eventually he gives up and walks out silently.
They laugh loudly and say to the waitress "He wasn't much of a man, was he?"
"No," she says: "and he's not much of a truck driver either -- he's just backed an eighteen-wheeler over a whole line of motorbikes."
