We never find out what exactly leads to Cartman needing the ambulance at the beginning, but whatever it was, it had to do with Kenny. :)
"we think it's because he drank Kenny's soul four weeks ago." - actually, three weeks ago. But this is the fourth episode in this run.
The preview in the plane references The Animal and the new movie The Hot Chick. The irony: a commercial for Rob's new movie The Hot Chick (where a college girl turns into him) aired during the episode.
John Edward. His show airs on UPN. In Los Angeles it airs on KCAL-9.
"Is that making sense?" - John Edward's actual line is "Does this/that make sense to you?" or "Do you understand this?"
"Uh d'eh'hm quiet, quiet down boys. It doesn't work that way." - It sure doesn't. It's at the host's whim what requests he responds to, not the clamoring of the loudest audience members.
Kyle was very fond of his grandma. He's still trying to do her proud.
Jewleeard is a spoof on Juilliard School of Performing Arts in New York.
Why didn't Chef or Liane take the pot roast with them as a carry-on item? It wouldn't have gotten lost so easily that way.
Stan's Lesson of the Episode refutes the boys' efforts at trying to reach Kenny just three weeks ago on the ladder to heaven. Kyle accepts the fact that Grandma is gone. If she's gone, then Kenny should be gone, too, at least now that he's out of Cartman's body. If Kenny's gone, he's gone, and no ladder or medium could get them to talk to him again.
BDIU - Biggest Douche In the Universe
Many of the aliens in the award ceremony remind me of the monsters in Monsters, Inc. Among the aliens you can see a few that have appeared in previous episodes, including the Marklar and the usual visitors. You can also see the Cherons, black-and-white aliens from Star Trek, "Let That Be Your Last Battlefield."
