An old man was eating in a truck stop when three rough-looking bikers walked in.As they passed the old man, the first biker pushed his cigarette into the old man's pie, the laughed and took a seat at the counter.The second biker picked up the old man's milk and spit into it. The third biker turned over the old man's plate before joining the others at the counter.Without saying a word to the laughing bikers, the old man put his money down, got up, and left the diner. One of the bikers said to the waitress, "Not much of a man, was he?"The waitress replied, "Not much of a truck driver either. He just backed his big rig over three motorcycles!"
