My friends brother used to work at a pharmacy and he got us this stuff for kidney tests that turns your pee bright blue. Me and my buddy took it and whent to a Broncos game at the old mile high where they had those long white trough urinals. We both went to each end during half time when the trough was full and took a bright blue piss from each end. All the other dudes were like WTF???????? Then everyone started freaking out because the urinal was orange and blue Broncos colors! Funniest shit ever
