he does piss at least once, maybe a couple times.. with the video moving so fast it's hard to tell but there is definitely a point around the 12-13 hour mark where it looks like he pisses in the corner, then 10 hours later he's laying in it lol. if you read the article it says a lot more about the ordeal, why he couldn't get out, why he didn't have his cellphone, some of the things he did while in there. Where's the masturbation and cigarette smoking? that should be in there somewhere too. He said he pulled out some button to keep a continous alarm and the sound of the alarm going off for so many hours started making him crazy. Also, 8 security guard shifts came and went and not one of the guards on duty noticed him trapped in there
! The best part is the end he just walks out.. no big spectacle, no jumping for joy, no awaiting loved ones.
