Getting stoned thinking there is a need for an after hours Olympics in TF2. Who can build their sentry the fastest? was the first one I thought of. Picture two engineers -- one red, one blue -- facing each other, building sentries. The one whose sentry gets blown up first, loses.
• An actual speed-typing contest to see who can come up with the most taunts.
• A game of chicken held in Well CTF where two heavies square off on the train tracks and the last one to jump wins.
• You start on one side of the map, burning. Water is on the other side. Can you make it in time?
