Wow. And he's supposed to be very nice.

Here's a funny anecdote about Rose Leslie (Ygritte):

The only annoying part of the whole business, she says, is that fans tend to be disappointed by her delivery. “I use a different voice — I put on an accent on the show — so when I say ‘You know nothing, Jon Snow’ in my own voice you get a furrowed brow from fans and they’re like, ‘That doesn’t sound like Ygritte.’ And then I got to go into [her character's] accent and do it and it’s a really long boring process for the fan and I’m sure they walk away wishing they hadn’t asked me because it’s such a kerfuffle.”
There was one time, however, where the catchphrase was used in real life rather awesomely.
Leslie was in Northern Ireland, one of the five countries where the upcoming season of Thrones was shot. She was sitting in a restaurant with a friend, and having a tough time deciding what to order. “And I said to the waitress, ‘I don’t know what I’m going to go for,’ and the waitress jumped in with the line. It was very funny; it was perfect timing. I gave her a high five.”
Leslie considers. “Actually, I wanted to give her a high five, but it would have been incredibly lame if I did.”
