Q: How do you make a herd of nerds stampede?
    A: Make them think computers are being stolen

I worked for our college IT department one summer, performing computer upgrades. The schedule was relaxed - one lab in the morning, 20 individual rooms in the afternoon, and plenty of downtime for personal coding projects + games. We just finished upgrading the Psychology department, and were waiting for the cafeteria to open. So we were probably goofing off. All of a sudden, our less technically inclined coworker Dave comes into the room and drops a bombshell:

"Who left all of the Dell boxes in the hallway? I just saw someone walk off with a couple of them."

We freaked! Someone stole computers?! We sprinted from our desks into the hallway, and stared blankly at a bunch of empty cardboard Dell boxes in the hallway.
