Baisant, mon vieux copain!! Vraiment j'n'savais point qu' tu parlais le Francais!! Vachement bien!!

This translates as

To the basement, my old co-pain! I have no point in saving your clothing who has French pearls. You're a good cow!

Of course, this translation doesn't take into account the French idioms, nuances, metaphors, hyperboles, verbs, nouns or body language so it might not be quite exact.
