I went to a poor high school and took Senior Level Anatomy and Physiology. Everyone received a cat that the class spent 6 months dissecting. All the dead cats in bags and smells of formaldehyde still haunt my memories some 7 years later.

I got my first apartment in 2001 and was all on my own to cook and keep a kitchen. I was a really lazy stoner back in them days, and rarely did my dishes until the situation was critical. One night I made a package of Kraft Macaroni and Cheese. You have to be a serious fatass to polish off an entire package of that stuff by yourself. I sure as hell wasn't up to the task, so I had half a pot of mac-n-cheese left and I just put a lid on it and set it on my dining room table. About a week later I was out of dishes and had to do them. I had completely forgot about the mac-n-cheese fiasco from the week before. When I took that lid off, I was slammed in the nose with the grossest f'ing smell in the world. There was green fuzzy **** growing all over the remains.

btw - I threw the pot away.
