Here's the Internet Movie Database listing for the show.http://members.tripod.com/~jessicarae/ootw/outofthisworld.html
This site also has some pictures and other things.
Yeah, I'm amazed how many people have never heard of this show, I used to watch it all the time when it was in syndication, and of course the theme song would be stuck in my head for days and days.
I remember one episode where Evie was playing baseball and using her time freezing power to cheat, so her dad took her powers away. And another one where she had a twin that was all punk (there's a picture of it on that one site) and another one where her uncle or someone picked Evie and her friend up, and they flew through space in a Winnebago (total Spaceballs ripoff there) and there was this weird houseplant and a lot of cans of Spam. It was a weird show.
