This is the second episode that was not aired in Japan. The first was "Chinpokomon".
Even though Cartman, Kyle, and Stan don't physically make it to Heaven, they wouldn't have found Kenny anyway since he was a Christian, and not a Mormon. This concept is explained in "Do the Handicapped Go to Hell?".
The McCormicks have a robot guard even though they are poor. It could have been bought with Kenny's life insurance premium, the half-million they got from Cartman as compensation for Kenny dying (in "Cartmanland") or for just something that happened to be there for some reason.
In Cartman/Kenny's flashbacks, everyone speaks the echoes.
In "Clubhouses", Stan builds a treehouse on his house's backyard. This treehouse is seen again in "Spookyfish". But, this episode shows Stan's backyard empty. The same error was made in "Quintuplets 2000", but they may have just taken the treehouse down after "Spookyfish".
When the news reporter first shows up, Kyle can be jumping on the ground and looking at Cartman. In the next frame, he is several inches from where he was before (this can be seen on southparkstudios.com; look at Kyle from 5:20 to 5:30).
