This 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 saying "NERDS NOT ALLOWED -- ENTER AT YOUR OWN RISK!" He goes in and sits down.
The bartender comes over to him, sniffs, says he smells kind of nerdy, asks him what he does for a living. The truck driver says he drives a truck, and the smell is just from the computers he is hauling. The bartender says OK, truck drivers are not nerds, and serves him a beer.
As he is sipping his beer, a skinny guy walks in with tape around his glasses, a pocket protector with twelve kinds of pens and pencils, and a belt 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 says not to worry, the nerds are overpopulating the Silicon Valley, and are in season now. You don't even need a license, he said.
So the truck driver finishes his beer, gets back in his truck, and heads back onto 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 freeway. He jumps out and sees a crowd already forming, grabbing up the computers. They are all engineers, accountants and programmers 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, felling 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 nerds were in season."
"Well, sure," said the patrolman, "But you can't bait 'em."
