What is the fake documentary that claims that Mao and Khrushchev were Chicago gangsters?

I saw this about 12-13 years ago. The claim is that Mao and Khrushchev had brothers who lived in Chicago. When the originals died, each the corresponding groups brought in the brothers to fool people into thinking that the original guy was still alive. However, the two guys in Chicago hated each other, and when each was ruling a given country it led to the Sino-Soviet split.

Yes, this was a fake, aired on April 1. However, I'm still trying to track it down and maybe watch it again.
