This guy was very lucky he ended up OK. To be fair, pretty much anyone who's ever had this sort of thing--looks remarkably like a "my parents are out for the night, I'ma have a few people over but keep it on the DL" type deal--boasts a story similar to this. Not all of them result in near-death, but the premise is simple. Young people are invincible, and invincibility must always be tested.
