go with fake pee, it worked for me. chances are no one will watch, so you don't need one of those fake penis things. just keep the little bottle next to your body, and by the time you pee it should be up to body temp. I believe the brand was "urine luck".

Do you mean Quick Fix synthetic urine? Urineluck is an additive thats dropped in a dirty sample. Both are made by the same company, Spectrum Labs.
