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, 
"You smell kind of nerdy.  What do you do for a 
living?" 

The truck driver says, "I drive a truck, and the smell 
is just from the computers I am 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 
said, totally shocked, "Why did you do that?" 

The bartender said, "Not to worry, the nerds are 
overpopulating Silicon Valley and are in season now. 
You don't even need a license." 

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"
