Is there a "Speak like a Roman" day?

I know, of course, that there is a "Speak like a Pirate" day, every September 19th and, no, you will not get me falling into piratespeak, oh no me hearties no ye won't!

"Sit iecundus tibi dies"

                                   

So, it seems very logical that we Catholics should indulge ourselves in a "Speak like a Roman" day - quid?

Now let me quickly explain, I am not a Latin scholar, I have forgotten what little Latin I did learn (but I can say the responses at Mass faster and more fluently in Latin than I can in English).

So, please disregard my following attempts.....

Loquerisne Latine?

Hic tibi placuitne?

Mea lingua latine est mala

Nauseo!

Opus est mihi medico!..........................Valete!................................Vobis pluramas gratias ago

Or, maybe we should stick to "Introibo ad altare Dei...."
