The notion that Vicki's skin isn't watertight is kind of lame, especially when it's implied that she's gone to beaches and pools without one spark of a problem.
Jamie: Can we go home now mom?
Joan: Yeah, let's do that.
Ted: Well, let's just be careful from now on on what we do with Vicki.
Vicki: (In a warped voice) Got an idea, stand her up in the middle of the yard and use her as a fountain. (Starts spittin' out water like a fountain.)
Doctor: This isn't the inside of a little girl! It's the inside of a computer!
The production title of this episode is "Everyone Into the Pool".
