@Killa Ounze that reminds me, I don't think I had food poisoning, but one time I did shit myself in the parking lot of the college I was attending. I was puking my guts out (no this was not related to drinking, amazingly enough) and someone called the nurse over and they took me to her office. I was sitting in her office waiting for my mom to pick me up, when that ol' diarrhea feeling came on so I walked to the bathroom in the nurse's office, and when I pulled my pants down there was brown all over the inside of my white undies.
The reason I don't think it was food poisoning was because the puking / diarrhea was only a couple times each. My brother has had food poisoning (I think more than once, actually), and he'd be firing from both ends all day long for the duration of multiple days. I chalked up to what happened to me to the stomach flu, because although I only puked/had diarrhea one day, I was perpetually nauseous for a couple days after that.
