i had a buddy who stole a tank from a dentists office. the med gas guy was delivering and he snagged it while the guy was inside the office....stuck it in his truck. he was going to a dead show in raleigh, nc and planned on selling balloons in the lot. we went out into a big field and huffed while burning some bud i had......that was some weird stuff! made your voice lower in pitch and if you inhaled and exhaled the gas thru a cigarette it looked like a rocket! i gave him an eighth for the road and he gave me a couple hits of flying eyeball. good times....good times. 1989 was a good year.
