I once worked on a mainframe project that had a tight deadline and required a lot of late-night work. This was before 'casual day' became popular and we all wore suits and ties. Whenever we would stay late, we would take off our ties and wear them as headbands, turning up the local Oldies station on the radio and doing the Limbo with a piece of masking tape between cubicles. We called ourselves COBOL Ninja Warriors -- upper management learned to avoid our area after 5pm.
