For me, it would have to be Boy Meets World. There are so many useful life lessons in the entire series.

NCIS. Just because. Haha. Gibbs, Tony, McGee... They are fun to watch and it's a good show. Plus... USA keeps then playing in marathons, so they are on when I need them most. Lol
I used to be obsessed with Dawson's Creek when younger, so if I was a teenager, would have answered with that.2

Batman the Animated Series. Twas my childhood.
As far as live action goes, Leverage. It was a show about a bunch of con artists who act like modern day robinhoods. Good blend of humor and action.
