- Unintentional Period Piece: Sheldon's comment that "maybe you have democracy now in your beloved Russia" has not dated especially well. The episode was made at a time when The New Russia was widely seen as basically democratic. Since then, Vladimir Putin has remained in power far longer than anyone expected and his regime has become increasingly authoritarian. It's a matter of some debate as to whether Putin's Russia is an actual dictatorship or just a very corrupt and authoritarian democracy, but the point stands that the issue wasn't even seriously considered in 2008.
