As a french-canadian living in Quebec ( the small airport scene ) or as I prefer to call myself: Quebecois.
I was more than suprise to hear some french in an american series. Even more when, after Gibbs complained as to why Ducky and La Grenouille were talking in french, McGee replies : They are in Quebec.
If anyone knows of the fact that in Quebec most people have french origins and speak french and are proud of it all. French is even the official language of the province ( French and English are official language of Canada ) Bravo to the writers for the good research although I suspect one of them to be Quebecois ( of origin at least )
Love the show, each episode is a delight but this one will be at the top of my favorite list.
