It wouldn't be a Game of Thrones parody if Hodor didn't get the best gag. The folks at Conan animated an opening sequence for a fake children's cartoon spin-off dubbed "Lil Thrones." The video starts poorly, hitting the same easy schtick about our favorite characters getting killed off, but picks up in the second half.
And yes, there are spoilers; it's a Game of Thrones parody in the year 2015.
The video riffs on the theme for the Muppet Babies, while Game of Thrones is indebted to HBO's Rome, a point my colleague Vald Savov made earlier today.
