Here's an excerpt. This made me laugh. I don't remember writing this, but it's been a few years. I examined the pizza slice, using my pharmacist trait and high intelligence.
Examining the slice of pizza more carefully, you see that the mushrooms are not normal mushrooms at all. In fact, they are of the genus Psilocybe. This species of fungi contains Psilocybin, a psychedelic alkaloid of the tryptamine family. Many people would call the fungi "shrooms." Ingesting the slice of pizza would undoubtedly lead to you hallucinating sometime in the near future.
It is impossible to tell how powerful the experience would be just by looking at the mushrooms.
