6. Little Debbie

Now in seventh grade, Paul's little sister Debbie (Torrey Anne Cook), who has a crush on Kevin, asks him to a cotillion dance when Paul weasels out of escorting her. Paul has "school spirit" on his mind by watching busty cheerleader Dina Delgado (Stefanie Scott) with Randy and Doug at the Friday night football game. At the dance, Kevin feels out of place when he and Debbie are chosen to lead in the "Sweetheart Waltz." But when Debbie wants souvenir pictures of their night, he ditches her for some fresh air.

While outside, the guys break the bad news: something slipped from Dina's uniform, revealing that she stuffs her bra. Heartbroken over Kevin's absence, Debbie finds him but her grandmother's pearl earring accidentally falls in the pool. Playing hero; Kevin dives in to retrieve it, asks her to dance, and gets their picture taken together. Guest-starring: Torrey Anne Cook in her first appearance as Paul's younger sister Debbie Pfeiffer. Recurring guests: Brandon Crane as Doug Porter; Michael Tricario as Randy Mitchell. Absent: Dan Lauria as Jack Arnold; Olivia d'Abo as Karen Arnold; Jason Hervey as Wayne Arnold; Danica McKellar as Winnie Cooper.
