When you gotta go, you gotta go. Sometimes, when you gotta go, you get to make beautiful music using an electric guitar urinal.

Guys need incentive to aim into the bowl, especially after a long night at the bar. Billboard Brasil created the Guitar Pee, an electric guitar/amplifier/urinal, to tour around Sao Paulo drinking establishments.

Here's the process. Drink a lot. Run to the restroom as the "Under Pressure" bass riff plays in your mind. Discover a guitar/urinal. Whiz on it to trigger some shredding electric guitar solos that would fit right in on a glam metal album.

Now flush and write down the number the unholy latrine-axe generates for you. Visit guitarpee.com on your mobile to listen back to your hair band triumph "MPEE3." Congratulations, you've just put the "pee" in masterpiece. Now wait for the groupies to arrive.

The marketing stunt vaguely ties in with Billboard Brasil's tagline, "Music. We know it comes from everywhere." Even your personal whammy bar, apparently.

I want to know why there's no GuitarPee for women. Is is not considered feminine enough? Perhaps we could get a toilet/baby grand piano combo that tinkles while you tinkle or a bidet/cello that plays selections from Bette Midler songs. I demand equal opportunity for musical micturition!
