Ah, college. The long hours. The tough assignments. The passive-aggressive room mates.
In my first "group house" we had a member who expressed his displeasure with us by turning the thermostat down to 50 at 1 am. I out-p-a'd him by waking up 5 minutes later and switching it to FAN so it'd still make noise but not freeze us/power bill us to death. Needless to say, that group didn't stay together very long.
