I've mentioned it several posts back, but Nick at Nite actually DID have it's own original shows during it's early years. There was Turkey TV, and National Geographic Explorers originated on Nick at Nite (and then moved to TBS). I've heard there was an "At the Movies with Siskel and Ebert"-type parody show which I can't remember the name of. And in 1991 there was Hi Honey I'm Home, which was sort of original and sort of not: Episodes premiered on ABC, and then were rerun the next night or two on Nick at Nite (I've read about this being referred to as "instant reruns"). ABC canceled the show before every episode was broadcast, so the remaining episodes premiered on Nick at Nite.
