This is a 100% true story.
Probably about 5 years ago, one of the girls I worked with at the time started selling essential oils and all that bull shit. She conned a bunch of other women I worked with into buying a bunch of shit. One of the things one of my friends bought was peppermint oil, which was in this little tiny bead sized balls. I was complaining that my stomach hurt one day, so she gave me a bunch because peppermint oil is supposed to help with that or something.
A few hours later, I go to take my mid afternoon shit. And I shit you not, my shit smelled like peppermint. It was very pleasant. As well, my asshole had that refreshing cooling feeling that your mouth gets when you eat something minty. It was dubbed "The Peppermint Experience". We both tried to replicate it many times after, but never could. No matter how much peppermint oil was consumed.
