If you were planning on showing everyone you know and their mothers the now infamous Game of Thrones episode from season one that includes a prosthetic of former president George W. Bush's head on a spike, you might be out of luck if you don't already own the DVD boxset - HBO has pulled the episode from all viewing platforms, including their streaming service HBO Go, iTunes, and OnDemand. As for current orders of the season one boxset, shipping has been halted until the scene can be digitally altered, and the offending commentary from showrunners David Benioff and D.B. Weiss removed. If you recall, HBO released a statement yesterday more or less saying that they were going to do this, so this should come as no surprise.
You can still check out the scene here on YouTube though, for now anyway - we're assuming it's only a matter of time before it's taken down. Otherwise, you're stuck with illegal downloads and exchanging copies of the episode on flash drives in dark alleys or something.
