Thanks to Jona I had the pleasure of google image searching the word "dermoid cyst." It's a cyst that has teeth and hair in it! I think I heard about those before, and then I strategically forgot about them.
Wikipedia says "Any teratoma near the body surface may develop a sinus or a fistula, or even a cluster of these. Such is the case of Canadian Football League linebacker Tyrone Jones, whose teratoma was discovered when he blew a tooth out of his nose."
I'll leave you with that. Night night!
