I get them all the time.  They are disgusting.  Now if you want to hear something even WORSE...

I have holes in the sides of my mouth.  Tiny holes, a bit bigger than the head of a pin.  I think it is from having strep too many times, but I don't really know.  Anyway, food gets stuck in the holes and then sometimes they contract and I can't get the food out for a while, and then when they open up again, I dig the stuff out with a bobby pin and it stinks.

Yeah, like I said...super gross.
