While the earlier music videos for Coldplay's fake "Game of Thrones: The Musical" -- Peter Dinklage's triumphant "Still Going Strong" and Nikolaj Coster-Waldau's ode to incest "Closer to Home" -- may have dragged out the jokes for far too long, the actual 12-minute short hits all the right comedic notes.

Produced for NBC's inaugural Red Nose Day telethon, dedicated to helping children living in poverty, the short goes behind the scenes of what Coldplay's Chris Martin bills as "the best idea we've ever head," but in reality is the most misguided musical since "Spider-Man: Turn Off the Dark."

"When I first heard about it, I was a little bit skeptical," confides actor Mark Addy, "but now I'm completely convinced it's a horrible idea."

The late King Robert Baratheon is joined in the documentary by cast members ranging from Diana Rigg and Emilia Clarke to Jon Snow (excuse me, Kit Snow Harington) and Iwan Rheon (who's beside himself with excitement). Narrated by Liam Neeson, it features Clarke singing "Rastafarian Targaryen," Harington belting out "Wildling" to the tune of "Wild Thing" and Rheon teaming with Alfie Allen and Charlotte Hope for an acoustic tribute to the relationship between Ramsay Bolton and Theon Greyjoy.

Alas, author George R.R. Martin's killing spree extends beyond the novels and the television series, meaning the world will never get to experience the wonder of "Game of Thrones: The Musical" ...
