At this point, it's almost impressive how little Kristen Wiig appears to know about one of the main characters on "Game of Thrones." The show is such a huge hit that even people who don't watch it tend to know a thing or two about Jon Snow and Daenerys Targaryen. Or, sorry, Karen, as Wiig informs us. She stopped by "The Tonight Show" "in character" as Khaleesi to promote her new movie, "Welcome to Me," and treated us all to some delightful trivia about one of our favorite "Game of Thrones" characters. For instance, did you know that Khaleesi is only sometimes British? Sometimes she has a bit more of an American accent. Somehow, we're guessing Emilia Clarke isn't too worried about her job just yet.
