Generally, the Real Programmer plays the same way he works — with computers. He is constantly amazed that his employer actually pays him to do what he would be doing for fun anyway (although he is careful not to express this opinion out loud). Occasionally, the Real Programmer does step out of the office for a breath of fresh air and a beer or two. Some tips on recognizing real programmers away from the computer room:

At a party, the Real Programmers are the ones in the corner talking about operating system security and how to get around it.
At a football game, the Real Programmer is the one comparing the plays against his simulations printed on 11 by 14 fanfold paper.
At the beach, the Real Programmer is the one drawing flowcharts in the sand.
A Real Programmer goes to discos to watch the light shows. At a funeral, the Real Programmer is the one saying Poor George. And he almost had the sort routine working before the coronary.
In a grocery store, the Real Programmer is the one who insists on running the cans past the laser checkout scanner himself, because he never could trust keypunch operators to get it right the first time.

Thanx to William Conway.
