Kenny WAS a dirty little bastard! When Stuart shows Kenny the Playboy centerfold, the crotch area is missing. I wonder what Kenny did with the remaining hole... Maybe Cartman answered that a few moments later: "I don't know. It's like my brain just keeps... jacking off."
Kyle's last name is misspelled again: Brovlofski. :)
The SNN newsroom looks like the Tynacorp headquarters.

Japan and the United States rushing to get their ladders into space recalls the Space Race between the USSR and the USA in the 1950s and 1960s - the USSR was the first with a man in space, but the US was the first with a man on the moon. Related to the Space Race is the theory that the U.S. moon landing was faked, as shown by the Japanese claim to reaching heaven first falling apart behind Nobu as he reports the claim. That theory is gaining more credibility the longer the U.S. does not send another man to the moon.
How come they didn't call Timothy Bottoms in to do his Bush impersoation? Price too high now?
How did Saddam really die? In "Not Without My Anus" Canadian farts killed him. In the movie, he was reportedly killed by wild boars. In this episode, Bush says the U.S. secretly killed Saddam months ago, then tells the UN the subsequent events, which occured back in the fourth season ("Do the Handicapped go to Hell?" and "Probably.").
"hard nipples!" - In BASEketball, Bob Costas tells his colleague to "feel these nipples" to show how excited he is over a BEERS victory. Excitement makes nipples hard. How come they didn't use a real echo effect when Kenny's point of view is shown?
The colors on the UN buildings are white, but not so in the movie.
God in this episode sounds a whole lot like Satan.
Nobby notes that Cartman drinking Kenny's ashes as a glass of flavored milk is like a dead man's friends making a soup of his body and eating it in the sci-fi book "Stranger in a Strange Land."
Kenny's presence in Cartman reminds me of Spock's presence in Dr. McCoy in Star Trek III: The Search For Spock
The Japanese text behind Nobunaga says "Sutajio C", or "Studio C."
Change from preview to final ep: The commercial for the new episode showed the boys emptying Kenny's urn dressed in all black. In the episode that aired they were in their normal clothes.
