Tenus
The diagnosis of teeth lodged deep within one's sphinct.
Woman: Doctor, I have a terrible pain in my asshole. And I have an awful discharge that reeks of undigested, old macaroni.

Doctor: Let me have a look. Why, there was a tooth stuck in your anus. My diagnosis, Tenus.

Woman: SHIT! I gotta call everyone I have ever had anal sex with now.
