Lege atque lacrima. Read-em and weep. — Henry Beard

Futue te ipsum et caballum tuum.

Claim it means: I've really got to take my hat off to you.

What it really means: Fuck you and the horse you rode in on.

Si hoc adfixum in obice legere potes, et liberaliter educatus et nimis popinquus ades.

If you can read this bumper sticker, you are both very well educated and much too close.

Taedium pellucidorum.

An eye condition that keeps you from looking at people's slides.
