You have to watch this !

I must confess it. I looooove this man! For the ones who don't know him, he's a British actor who became famous for his tv series House MD (aka Doctor House). Mind you, this tv show was American, and he had to modify his British accent to perform his character!
Hugh Laurie: excellent actor   -  House MD : excellent tv series!
This video shows him and Ellen Degeneres playing a game of American slang versus English slang.  How many of these do you know? are you more American or Brit?
