Jon Stewart was mentioning Big Brother as the government last night's episode (December 14) and then decided they don't need a Big Brother but a Big Sister... in comes footage of the episode "Blood Ties" of Season 5 of Joss Whedon's "Buffy the Vampire Slayer" where Buffy beats up Glory for bothering her sister Dawn. 'Big Brother' is a reference to the novel 1984 (written in 1949 by the way) by "George Orwell" also known as Eric Arthur Blair. For those to young to know, 1984 is about the future as it was written 1949 where the government, or Big Brother would gave the public no privacy at all or freedom. Kudos to Jon and crew to reference Joss' Buffy.
