People's Under That Age of 18

What gigs have you done? And where? Whats the craziest thing you've ever seen at a party/gig.

As for me, I do a bunch of house parties, 2 car shows every year, and large sporting events at my high school.
The craziest thing I've ever seen at a gig was a paintball shoot out at a party. A bunch of guys loaded up their Tippmans, put on paintball masks, walked in, unloaded on everyone in the party, then promptly disappeared into the evening . No cars, bikes, scooters, all on foot into the woods. Guerilla pros if you ask me XD. The cops were called and the "gunmen" were nowhere to be found, the police combed the area.
The police then departed one by one until it was about 1130 and they were all gone. After the last car drove off, all the "gunmen" stylishly walked out of the woods laughing their asses off at everyone who was still there.

Apparently they had planned all of this. They had a man in the house across the street keeping them informed of the position of the officers as they all hid in a storm drain that empty's into a creek in the woods. While the owner of the house was beyond pissed, everyone else was amazed (and terrified at the same time).
