BUSTED
Well, kind of.
It's very possible that you could pick up pink eye by your pillow being farted on, but that's because it is caused by bacteria. It infects the eye and is fired up easily. As I said, it's possible that that could happen, because farts aren't exactly clean, so they could easily infect your eye, but that's not 100% guaranteed, and if I were you, I wouldn't be going around farting on peoples pillows.
