lol i say do the piss idea just take a plastic bag of urine to the bottom of your leg (that way it can stay warm) and when they want your piss just take it out of the bag and put it in the cup if you want i can find some pee in a bag and send it to you...im sure there's one clean person around here somewhere
that or you could do the workaholics idea and pee in EVERY urine sample so they'll think its something wrong with the tester (if they have multiple urine samples)
