This is not necessarily the worst but def. the most mind fucked I have ever been while tripping. I was in high school and a group of us decided to take some shrooms and watch Princess Mononoke. I must say, one of the best movies I've ever seen while under the influence of hallucinogens. The beauty and nature makes it a great combo plus it's just a bad ass movie. So after a few hours we finish the movie and are feeling really great. My friend lives on a pretty big plot of land so we all decide to go outside and enjoy the rest of the trip on a beautiful summer day. Meanwhile, his mom decides to come outside and see what we were up to. We weren't really too worried about it, she was extremely cool and tolerant of our recreational drug use but we still tried to play it cool. She comes over to talk to us and we are tripping pretty hard at this point. Using every ounce of myself trying to maintain a coherent conversation with my friend and his mom, I suggest that he come visit me (I lived somewhere else at the time)

His mom looks at both of us and says, "What does that have to do with the price of bread?" Literally blew my fucking mind, my friend and I both looked at each other and immediately ran in opposite directions. Meanwhile she slowly walks away with her hands behind her back and the most satisfied look on her face. Touche mom, touche....
