You're up for that big job opportunity and suddenly "The Man" wants to pry into your "totally under control" chemically-enhanced lifestyle. Enter the Pissinator: everything you need to sail through a piss test, from designer bladder brew to an anatomically correct rubber dong.
According to the website, the device is absolutely not intended to be used for any illegal purpose, specifically drug tests. Their competition, the Whizzinator, got taken down by a federal prosecutor for selling drug paraphernalia, so you can see how the Pissinator people have to keep it on the down low (if you'd like to amuse yourself for an afternoon, try to imagine just one non-illegal, socially acceptable use of a prosthetic penis that fires someone else's urine).
All you do is strap the bag of piss under your shirt, snuggled all comfy under your armpit. A handy heat pack will keep the brew at the right temperature, and you can deposit your sample with a flow so "simple and realistic that even your own mother would not be able to detect that it is in-fact simulated." Oh, that's what it's for. So you can win the annual family Thanksgiving Piss Distance Contest without your Mom (who referees the event) noticing you're cheating. So there's one use right there.
