Oh yeah? But can the Doctor speak Klingon?

probably not (and neither can I before you ask), but when we were watching episode four of the Tenth Doctor (the girl in the fireplace), there is a sequence where the doctor speaks French, and let me tell you... Oh boy.. I thought that Ms. Mysterious liked me, and was charmed by me but... damn... she heard the doctor speak and well... let's just say that I had to get a mop to clean her mess :)

Okay, fine I exaggerate, I just went for a towel. (great episode though!)
