About The Simpsons (1989) Season 18, Episode 22 : You Kent Always Say What You Want

At the Simpsons' annual dental check-up, Lisa gets an education in dental hygiene from a video starring Ludacris (guest voice Chris "Ludacris" Bridges) as Luda-Crest, a tube of toothpaste with a talent for rapping. The Simpsons stop for ice cream on the way home from the dentist, and when Homer purchases the 1-millionth ice cream cone, he is featured on Kent Brockman's nightly news program. However, the innocent interview turns into trouble when Brockman uses a shocking expletive and Ned Flanders wages an anti-indecency campaign. The Simpsons take in the dejected Brockman, and he and Lisa begin to devise a scheme for the anchor to make his comeback. Meanwhile, Principal Skinner ushers the students of Springfield Elementary into a new era of sneaking, snooping and snitching with the opening of the school's CTU Counter Truancy Unit with Lisa heading up the operation. Homer is sent on a mission to dispose of a container of yogurt so far past its freshness date that it could be toxic, but the reeking yogurt falls into the wrong hands. With the help of Jack Bauer (guest voice Kiefer Sutherland) and Chloe O'Brian (guest voice Mary Lynn Rajskub), Bart and Lisa must stop bullies Dolph, Kearney and Jimbo from releasing the ultimate stink bomb at the school's annual bake sale. Guest Stars: Ludacris, Maurice LaMarche,
