I’m really showing my age here.
The best thing ever on CN in Sunday nights was Mr. Spimm’s Cartoon Theatre.
A chance to see shorts and features you’ll never see anywhere else. John Korty , Norm McLaren, stuff way beyond typical Disney fare.
Also a great oasis for theatrical shorts from aWarner Bros, MGM, and Hanna Barbers shows, until it became the Scooby Dumping Ground.
I never saw complete series, but there are a few individual episodes I really love, of Ed, Edd and Eddy, Cow and Chicken, and Angry Beavers.
As CN became the Scooby Network, Biomerang came along, but even that fell by the wayside.
