When I was little I was a huge fan of Mister Rogers' Neighborhood.
Later I watched the lineup in KevShmev's early post - Cosby, Family Ties, etc. My mom and I watched Cheers together from start to finish, all those years. Loved Night Court too. I loved watching certain re-runs like All in the Family, Happy Days, Laverne and Shirley. We loved Mork & Mindy.
For awhile there was a Dungeons and Dragons cartoon and I liked that a lot, but not as much as Scooby Doo. Nothing is as awesome as Scooby Doo meeting the Globetrotters, or Don Knotts, etc.
