Nerd Season

A truck driver hauling a tractor trailer filled with computers stops for a beer. As he approaches the bar, he sees a big sign on the door reading, "Nerds Not Allowed -- Enter at Your Own Risk."
He enters the bar and sits down. The bartender comes over to him, sniffs him, says he smells kind of nerdy, and 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 okay, 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 said not to worry, the nerds are overpopulating the Silicon Valley, and now they are in season.
"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. Remembering what had 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 says, "What's wrong? I thought nerds were in season."
"Well, sure," says the patrolman, "but you can't bait 'em."
