One time, when I was very young, probably around 13, I saw a nearly completely used up bar of soap in the bathroom. I didn't know what suppositories were at the time, but for some reason I decided to put it in my bum. It hurt like hell, I had to push it out, and a lot more stuff came out with it! It hurt for days afterwards, and I have never put soap anywhere near there since.
One question Gabumon - "stuff" meaning excrement, or anal mucus / blood
