friends of mine managed to get a proper, BIG cylinder of N2O for a party once... unfortunately, the effects from the tank were never as good as those from a standard bulb-erator but there is noting like being able to have 4 people sucking off pipes at the same time
back on topic: I missed seeing the Leary show aswell... only heard about it today I'd love a copy too from someone if it isn't too much trouble. Tho, if someone can get me a copy, I'd be more than happy to digitize it and convert it to DivX.
