Select Source

Bette finds a letter in the recycling bin, and shows up at Rose's school as a volunteer mom on the same day Olivia Newton-John is helping out. Olivia spends the day avoiding Bette, since (unknown to Bette) Olivia's held a grudge ever since Bette locked her up while she was supposed to be at an audition for ""Grease."" After fending off the head of the school, who's trying to solicit a screenplay, Bette notices that Rose got her belly-button pierced, much to her mother's dismay. Meanwhile, Connie shows up to get some promotional CDs autographed and winds up spending the day in the girls bathroom doling out advice to the adolescents.
