If anyone said that you could disguise alcohol by eating your own feces, they are full of it. In Toronto a man was arrested and taken to a local police station for testing. On route the man, urinated, vomited and defecated in the rear seat of the squad car, to further his "I'm not drunk" plea. Once at the station, the man took a hardy helping and placed it in his mouth to try and trick the machine. I didn't work. He's due in court on May 12 hopefully with a few Tic-Tacs.
