My parents never watched either, but I did catch a little "Hee Haw" at my grandparents' house when I was little.
Most of my Lawrence Welk viewing actually happened more recently. I don't remember exactly, but I'm going to say that for about a two year stretch, approximately ages three to four, my daughter found the "The Lawrence Welk Show" absolutely mesmerizing. And I didn't mind watching it with her one bit. With kitsch levels fluctuating between amusing and downright surreal, and the occasional flash of real musicianship, it's actually a pretty entertaining watch.
that beats the House of Mouse anyday
