For this one, I'd have to say "That'll Be the Day" is one of them (it started the obligatory musical episode in the following seasons), because it showed the kids getting out of their usual shells. I also liked "Psyched Out at Fillmore," as well. The innovative one was "Play it Again, Woody," because it incorporated many different scenes and utilized flashbacks well.

I agree. That'll Be the Day is a really fun episode cause they do Grease. I also think that Video Activity with The Future So Bright is fun too.

I like the ep. (can't remember the name) where they did a production of "Little Shop of Horrors"!
