Watch the kept blooper in the initial kitchen sequence where Pennington nearly slips on spilt milk on the floor. At the end, Vicki laughs without a face (just eyeballs and teeth!)
Ted: (After revealing Vicki with just her eyes and teeth) Say 'hi' Vicki!
Vicki: Hi mom. Hi Jamie.
Joan & Jamie: Vicki?!
Vicki: It ain't Punky Brewster!
The production title of this episode is "See No Evil".
