Friends - for it's cool theme song!
The Wonder Years - nice use of an old song; great idea to use a "home movie" format
All in the Family - I like how characters who are in the show sing the theme
Drew Carey - Cleaveland Rocks!!!!
The Jeffersons - I could just sing "movin' on up" all day long...
The Nanny - great use of a cartoon opening (I've heard that Rosie O'Donnell got the idea for her cartoon opening from this show)

Fresh Prince, FOL, Diff'rent Strokes and My Wife and Kids- I like the fact that has no opening and goes straight into it.
