dunderball

any non-computer game played during work hours to pass the time.
From the "The Office" episode "office olympics" - throwing paperclips into someone's coffee cup, bouncing a NERF football against the wall, taking bets on who will exit the elevator next, etc etc.

I'm bored and the server is down - you up for some Dunderball?
