Me: Are you sure it's not "penises" instead of "penii?"
Johanna: Well, the plural of anus is "anii" and...or, wait. Is it?
Zanna: I've never been in a situation where there's been more than one anus.
(That is to say that Zanna has never been in a situation where she's needed to refer to more than one anus, since the literal translation of her sentence is clearly false in the given context.)
