Vinegar for me. Once in my life had to take a piss test for employment, and vinegar is a great cleanser for ridding toxins in your body, but after half a mouthful, holy shit I alsmot barfed. It was so gross. I failed the test too by the way. They found a detox drink in my system (those smart bastards!).

One time I was with Lucy and I drank a day old coffee that someone nicely used as an ashtray. I didn't notice it as colors were flying by me at lightning speed, but the thought of it is not very pleasing.
