Of course, we just called it "Starcraft class". It was really just a computer lab to which we had semi-authorized late-night access.
During one particularly late night of gaming (I believe it was about 7:00am on July 4th, oddly) we heard the beep-beep-beep of the keypad and froze in our seats. The door swung open and a woman stepped halfway through the door, halting when she saw us. We stared at each other, wide-eyed, for a few moments before she said, "What the hell are you doing in here? How did you get in? I'm calling security! What are your names?"
My friend responded first. He pressed Alt-F4 and stood up, grabbing his headphones. "No thanks," he said, and walked past her out the door. She followed after him, yelling that he couldn't leave and was in big trouble. We scurried out behind and headed for the other exit.
He's still kinda my hero.
