Reminds me of a team building conference many years ago. The exercise was supposed to be a paintball fight, where the names of the team members were "randomly picked out of a hat". When we saw that the one team consisted of management and senior supervisors and the other team consisted of others, we all just randomly fired off all our paintballs and went to the pub, leaving the management team trying to convince the organisers that they weren't going to get paid because they could not control people. Actually, it was a great team building exercise in the end.
