Oh, for old shows that I watched when I was younger that aren't around that I loved...
Are You Afraid of the Dark?
Beetlejuice (prolly my favorite).
Wild and Crazy Kids
Get The Picture (If you have BOOM or whatever channel its called that I have it's on at 6AM though)
Salute Your Shorts
Doug
Kids Incorporated
ADVENTURES IN WONDERLAND!
Bananas In Pajamas
Inspector Gadget (the show, not the movie with matthew broderick (he went from godzilla to that and it was weird.))
Muppet Babies.
I was also the huge-hugest fan of Happy Days and The Wonder Years. They don't play those on TVland, but they DOMINATED Nick-At-Nite when I was younger.
