Equinox

Huginn: O lente, lente, currite noctis equi!

Muninn: I am sure that equinox has nothing to do with equines, and you know this.

H: I was just horsing around.

M: Ignorance and cheap wordplay are equally noxious, my dear.

H: It's that time of the year, or at least one of two times.

M: Well, yes, it is. And two times two makes four.
