I think my favorite episode from season one is The Diner Show, because first of all it's really funny. And I like how all the characters are a big part of the episode. The kids are trying to distract Charley while sneaking out party guests, and Hope and Faih are at the diner. BTW, this was the first episode I ever saw.
My favorite episode from season two is Hope Couture, again because I like how all the characters are a big part of the episode. The fashion show plot is really funny. And I like it when Charley and Justin are camping.
And my favorite episode from season three is Faith Knows Squat, the whole plot is very funny/I like it when they try to get even with each other, and Hope was hilarious.
