As a teambuilding exercise, the Finnish energy firm St1 had 130 employees wear and use one pair of skis. The custom-built skis (yeah, you can't find these in sporting goods stores) were 140 meters long.
The workers strapped themselves into the skis at a track in the city of Lahti, then skied together for 130 meters without a single foot slipping its bindings. This earned St1 a Guinness World Record for the largest number of people attached to a single pair of skis.
