During college, in my sophmore year, I worked at a Taco Bell that was located in our cafeteria.
One day, I took a shit, packed some of it in a plastic bag, and let it sit until it dried.
The next day, before heading in to work my shift at Taco Bell, I divided the dry shit into tiny bits.
While at work, when no one was looking, I took pieces of the shit and sprinkled it in the tacos.
I did this only for mindless fratboys and wealthy eurotrash that walked the campus with their noses touching the sky.
