For those of you with a subscription to HBO, tonight has probably been on your calendar for a while.  Yes, that’s right, Game of Thrones Season 3 premieres tonight.

If you’re really die-hard, you’re probably watching HBO2 and their marathon leading up to the premiere tonight.

The true show of support in the modern era, though, isn’t watching the show, it’s changing your Facebook profile picture.  Need help finding a good new Facebook pic?  A website has been set up to help you make your own custom family coat of arms!

So grab a leg of mutton, build your coat of arms, and turn on the magical “Picture Box” at 9 pm Eastern Time tonight and watch the majesty of HBO’s art directors at work.
