A little guy is sitting at the bar just staring at his drink for half an hour when this big trouble-making biker steps next to him, grabs his drink, gulps it down in one swig and then turns to the guy with a menacing stare as if to say, What'cha gonna do about it?
The poor little guy starts crying.
The biker laughs and the little guy, feeling humiliated, walks out of the bar.
After a while, the biker turns to the guy next to him and says, "Can you believe that little guy who was in here? He isn't much of a man!"
The other guy replies, "He isn't much of a driver either. When he pulled away from the curb, he ran over somebody's motorcycle."
