Just a story: My friends and I built a beer-loan agency for a burning-man event. We had people fill out forms to get a beer loan, told them their credit was too low, sent them on a quest, then gave them a beer on return.
This music is what we used for our fully fabricated waiting-room office. At one point a guy with a legal degree from Yale came to question our paper-work, and proceeded to litigate from the bar down the road we'd sold our failing business to.
