We used to get the show on the local PBS. Dh and I would laugh our heads off. We thought it was great because it was clean! Haven't seen it in the last year or so. Will look for the dvd.
Yeah, Detroit PBS was the place that we had seen it several years ago.
Looks like they can be ordered directly from the show's website, or via Amazon.com. Wife has given her okay for ordering a couple of the episodes we really liked. They're like $9.95 each.
