I <3 Game of Thrones!
If you haven't seen season one of like the most awesome show on TV, then you obviously live under a rock or something. You need to fix that by getting a TV under your rock and HBO, because winter is coming!
Here's the season 2 "Cold Winds" teaser trailer:
The only other thing that has been this exciting was the "Batman: Dark Knight Rises" trailer when I went to see "The Girl With The Dragon Tattoo," last evening.
Also, if you're awesome like me, you can watch this on the go with HBOGO or whatever the app is called. You're going to need it because winter is coming, etc., and you don't want to be caught in the snow (Read: Stuck at work in Florida) without the ability to watch this show!
Here's the link to the app: http://www.hbogo.com/
