Hardrock, Coco & Joe and The Forgotten Christmas Specials
Anybody that grew up in the Chicago area will remember that WGN aired TV Christmas specials other than "Rudolph the Red-Nosed Reindeer" and "Santa Claus is Coming to Town".
The animation and overall quality of these aren't as good as the Rankin/Bass specials. But something about them reminds me of Christmastime. If you remember watching these back-to-back-to-back when you were a child, show them to your kids so that they know what we had to deal with.
