In my freshman year of high school, I ordered a pizza slice. I started eating it and I don't know why, but I had the weirdest feeling to look under the pizza. Good thing I did, there was a big patch of CLOTH cooked into the bottom of my pizza. It wasn't stuck, it was COOKED into it. How would that even get in there. It was a bit more than an inch high and wide.

I was completely disgusted (I couldn't eat pizza of any sort for a week, which is huge for me, since I absolutely love pizza) and I started yelling at the lunch ladies about how if I have a big patch of cloth cooked into my pizza, should I be expecting some sewing needles next week? They didn't even give me a new pizza. xD
