This truck driver hauling a tractor-trailer load of computers stops for a beer. As he approaches the bar he sees a big sign over the entrance saying "NO NERDS ALLOWED -- ENTER AT YOUR OWN RISK!"
He goes in and sits down. The bartender comes over to him, sniffs and 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 said not to worry, that nerds are overpopulating Silicon Valley, and they are now "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. As he jumps out of the cab he sees a crowd quickly forming, grabbing up the computers. They are engineers, accountants and programmers; all 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 they are..." said the patrolman, "But you can't bait 'em!"
