Are you old enough to remember The Rocky & Bullwinkle Show? I loved Rocky and Bullwinkle when I was a kid. The show was a product of its times though, as evidenced by Boris and Natasha, the Cold War Soviet spies constantly being thwarted by Our Heroes.
Once the Cold War ended, whatever happened to Rocky and Bullwinkle?
It seems that someone in Russia is still keeping tabs on them.
Because of this new danger, I think Rocky and Bullwinkle have gone underground, emerging only occasionally to leave coded signals of their ongoing presence amongst us.
