A truck driver, hauling a tractor-trailer load of computers, stops for a beer. As he approaches the bar, he sees a big sign on the door that says, "COMPUTER NERDS NOT ALLOWED - ENTER AT YOUR OWN RISK!" He enters and sits down.
The bartender comes over to him, sniffs, and says that he smells kind of nerdy. He then asks him what he does for a living. The truck driver explains to him that he drives a truck, and the smell is just from the computers he is hauling. The bartender serves him a beer and says, "OK, truck drivers aren't nerds."
As he is sipping his beer, a skinny guy walks in wearing a pair of glasses with tape around the middle, a pocket protector with twelve kinds of pens and pencils, and a belt that is at least a foot too long. The bartender, without saying a word, pulls out a shotgun and blows the guy away. The truck driver asks him why he did that.
The bartender replied, "Don't worry. The computer nerds are in season because they are overpopulating Silicon Valley. You don't even need a license."
So the truck driver finishes his beer, gets back in his truck, and heads for the freeway. Suddenly, he veers to avoid an accident, and the load shifts. The back door breaks open and computers spill out all over the road. He jumps out and sees a crowd already forming, snatching up all of the computers. The scavengers are comprised of engineers, accountants and programmers - computer geeks. Each of them wearing the nerdiest clothes he has ever seen.
He can't let them steal his whole load. So remembering what happened in the bar, he pulls out his gun and starts blasting away, killing several of them instantly. A highway patrol officer comes zooming up and jumps out of the car screaming at him to stop.
The truck driver said, "What's wrong? I thought computer nerds were in season."
"Well, sure," says the patrolman, "But you can't bait 'em!"
