Freddie tries to be the "cool" uncle by taking Zoey to see "The Rocky Horror Picture Show." But when Zoey tries to impress her friends by inviting them along, and his best buddy, Chris, dresses up as Dr. Frank-N-Furter, Freddie ends up with more than he bargained for. Meanwhile, Allison and Grandma are stuck at home handing out candy, so they entertain themselves with a drinking game.

Freddie and Chris return home from a night out and walk in on his niece Zoey's slumber party. Chris jumps in and helps one of her 13-year-old friends with her boyfriend crisis, while Freddie meets Kaitlyn, the mother of another girl, and they hit it off right away. But when Freddie tries to date Kaitlyn, he learns he has to win over her daughter first, which makes Zoey jealous.
