"Roger Ebert Should Lay Off the Fatty Foods" is the eleventh episode of the second season of the American animated television series South Park.
Cartman—having snuck out of the planetarium just before the brainwashing—sings the Cheesy Poofs song and gets selected for the audition; he advances further after cheating and browbeating his way past the other contestants, including one who is poor and in need of food.
After the other audition finalists "unexpectedly" go to work at the planetarium, the judges reluctantly select Cartman to sing the Cheesy Poofs song on television.
However, in the middle of the process, Cartman, upon discovering the other boys missed his commercial, angrily kicks the star projector and proclaims that "Planetariums suck ass!".
A full blast of the mind control machine gets sent into Dr. Adams' brain, rendering him as a mindless shell collapsed against a wall.
All 18 episodes of the second season, including "Roger Ebert Should Lay Off the Fatty Foods", were released on a DVD box set on June 3, 2003.
