I can't find the person who made it, if anyone does, please do let me know so I can credit them.
There is a magic trick involving a russian roulette type game with test tubes, 5 of which contain apple juice/beer, 1 of which contains urine. Someone was marketing it under the name Urine Luck back in the day, but now that is the name of a detox product with a much larger market that fills the google results. I really wanted to find a video of someone performing that trick to paste here, and I am sure there is one out there because it was a very popular trick, but I was unable to find one. I leave this comment instead, in case someone's google-fu is better than mine.
I've heard a version of that, where you take a glass of orange juice and a glass of water and bet the person that they can't taste the difference when blindfolded. They sip the water, then you switch the OJ glass with a glass of whole milk. The difference in the expected flavor is apparently enough to make some people vomit, while most people just find it shockingly unpleasant.
