Stars are making fun of the hated boy king, with Eli Roth tweeting "Joffrey finally found the cure for his parents' incestual desires: himself."

Forget Comedy Central. King's Landing really knows how to throw a roast.

HBO is holding a two-day social media roast for King Joffrey, the hated boy-king played by Jack Gleeson on Game of Thrones. On Thursday and Friday, fans can tweet their best Joffrey zingers with the hashtag #RoastJoffrey.

While Joff has a habit of using his crossbow against those who displease him, people partaking in the roast can probably count themselves safe. So far, a number of the show's stars have weighed in (see below), while HBO is curating the best Facebook, Twitter, Vine and Instagram posts at RoastJoffrey.com.
