The opening episode of Growing Pains's fourth season focuses primarily on Ben (Jeremy Miller), youngest member of the Seaver family, and Ben's extremely pregnant mother Maggie (Joanna Kerns). Fretting over the prospect of inviting a girl to a Halloween party, Ben decides to ask out his lifelong friend Jenny--played by Candace Cameron, younger sister of series star Kirk Cameron (Mike Seaver)--with the understanding that it isn't a date...really it isn't...honest. Meanwhile, Maggie's mood swings have become so dramatic that her husband Jason (Alan Thicke) is thoroughly spooked, a fact that wreaks havoc at the couple's weekly Lamaze class. This episode marks the world premiere of pop star Tiffany's hit single "All This Time". ~ Hal Erickson, Rovi
