My wife and I loved this episode so much that we hoped to buy the entire series on DVD or Blu-Ray disc (BD). We couldn't find it, and to date it does seem unavailable, which is sad because we would have purchased it in a second.
It was clean and funny and close-to-home; we could relate! Great episode from what must be a great series. The actors who play husband and wife were actual spouses, which may explain why their interactions seemed so close-to-home! My wife and I felt like the lives we were viewing were reminiscent of our own....
If you can find it, we'd highly recommend you watch it! We saw it on a local 'classics' TV station. Very worthwhile.
