Here are a few to wet your taste buds:
- a thought-provoking one: Deorum iniuriae Diis curae. ("Offences to the gods are the concern of the gods." - Perhaps very apt in these times of religious tension.)
- a kind of meta-proverb: Quidquid latine dictum sit, altum videtur. ("Anything said in Latin sounds profound." )
- a weird one: Temeas simium meum. ("Hold my monkey!" - Eh?)
There are plenty of others, go and discover.
Not to be the local pedant, but just a quick note on the "monkey" quote. Don't know where this came from but "temeas," to my knowledge, is not a Latin word - "teneas" is and signifies "may you hold," which in the quote would roughly translate as "may you hold my monkey" (I don't believe this has any notable usage in historic Latin).
"Teneo" (Latin: hold) comes into English with words such as "tenor" (one who holds (a note)), "tenacity" (the quality of holding on doggedly), "tenant" (one who holds possession), many others.
Well, I guess I am the local pedant (see, e.g., http://grellas.com/article_word_origins_fero.html).
