Programmer smoking..

 A guy is standing on the corner of the street smoking one cigarette after another.


A lady walking by notices him and says "Hey,don't u know that those things can kill u? i mean, didn't u see the giant warning on the box?!" 

“That’s OK” says the guy, puffing casually “I’m a computer programmer”

“So? What’s that got to do with anything?”                                          


“We don’t care about WARNINGS. We only care about ERRORS.”
