ACK! Apparently, string cheese sticks to paper... I was doing calculus hw just a sec ago, and I had to lay the stick of cheese in my left hand down so that I could operate my calculator. Well, I placed it down on the book, and when I tried to pick it back up again, it like stuck to the paper and left a nasty looking film of cheese on the page. Yuck. I wiped it up, but I think it's gonna leave like a grease stain, haha.
