Good to see that student piss-artistry is still an activity pursued with some vigour. But don't think you're breaking new ground, in the broad sense. I was doing it in 1963. In those days puking it up provoked ridicule and humiliation, equivalent to "touching cloth" in a farting competiton. Does a similar culture prevail today?
[ZK] Well, there's your problem. The trick is not to eat for at least 18 hours before you go on a binge. It won't make you less sick, but it's a lot cheaper.    ;-)
