The Guest Stars of
"Roger Ebert Should Lay Off The Fatty Foods"
by Wild Willie Westwood
Dr. Adams
He runs the Tantalus V Observatory, which provides a laser show and other things for the study of space and the planets. But there is a dark side. When he has a captive audience entranced by the zodiac as it moves across the domed ceiling, he activates a neuroneutralizer with which he can send subliminal suggestions and compel people to return to the planetarium. The planetarium is in danger of closing, since new technologies have taken the magic out of stargazing, so Dr. Adams is doing everything to keep people coming back.
Van Gelder and Missy
Van Gelder used to do "volunteer" work for Dr. Adams before he realized what Dr. Adams was actually doing to people who visisted his planetarium. While the class went to the planetarium for a show on the stars he snuck into the bus and begged to be taken away from the planetarium when Stan and Kyle saw him pop up in front of them. He recovers under Nurse Gollum and Mr. Mackey's mind meld. Missy does the work now.
Cheesy Poofs Commercial hopefuls
Tommy Fritz, Hopeful Peter, Cosette Thénardier and her mom
These were all kids, except for Cosette's mom, who tried out to sing the Cheesy Poofs commercial song. Cosette was eliminated when Cartman told her that bread was being given away outside. Cosette and her mom ran out to get some (psych!), and he locked the door behind them. The other kids were eliminated when they went to do volunteer work for the planetarium. Cartman won by forfeit, and he got maybe ¼-second on-screen. There's a kid on the Grant Elementary dodgeball team that looks like Tommy Fritz.
Cheesy Poofs announcer, Callback Judges, Cheesy Poofs director
The blond is the Cheesy Poofs spokesman and cameraman. He tapes all the kids and takes the auditions to the judges so they can decide whom to elect as kid spokesman for the cheesy treat. The judges choose five finalists and listen to them. Apparently, Cartman was the last and only choice the judges had, since the other four finalists had taken volunteer jobs at the planetarium. The director then tapes the final commercial. The director has problems with lighting and with Cartman's shoes.
Det. Barnaby Jones, An Asian Reporter
Det. Barnaby Jones is the main character in Barnaby Jones, which for some reason Mr. Garrison is showing the class. The Asian reporter does look somewhat like Ricardo Montalban, but that's it. He doesn't have Montalban's flair.
