I should be embarrassed to admit this, but Beverly Hills 90210 (the original) and The Waltons.
The Golden Girls!
I don't care how down I am, that show always picks me up.
Knots Landing.
I started watching over 1/2 way thru the series in 1990ish. In 1996 or so one of the cable channels ran the series from the beginning. I worked mids so I would record when I was sleeping and catch up on it later in the day.
I loved that series.
Roseanne (favorite show ever)
Seinfeld
Mama's Family (why won't they release the rest of this show on DVD?! I only have the first season. Doesn't show on TV anymore either)
I Love Lucy
eta My So Called Life (Jordan Catalano!)
Sabrina the Teenage Witch.
Love love love that show!
The Golden Girls!
I don't care how down I am, that show always picks me up.
Full House-Please don't laugh.
Spongebob-My 3 year old DD is nuts about that show.
