Love Alton Brown's old show, watched it every time it was on Food Network when I had cable, also have enjoyed many a Hee Haw in syndication but haven't heard of the other two. Will have to look them up
My favorite, watched Baa Baa Black Sheep from Netflix - using the DVD service, love it, and watching Star Trek Voyager on Netflix on the new Apple Tv love it too. Probably my current all time favorites, followed by Leave It to Beaver and Dick Van Dyke (just started them on Netflix too) seems I should have been born years earlier so I could have enjoyed them at the same time everyone else was.
