Cruising by our offices, morning commuters in the downtown area did a double take recently as they witnessed BW staff lined up to take their turn for distance, accuracy and overall spew style. Bashfulness was checked at the door as the competition slowly simmered to an all-out bout of sailing pits. Some went for distance, while others hocked it into a bucket to win fabulous prizes and the fleeting admiration of fellow co-workers. There is a science to everything. It takes just the right angle and force. The projection had to be strong, yet subtle. Some contenders were harder to beat, what with the distance their saliva-greased pit flew from between pursed lips. The result: A good team-building exercise in expectorating.
