I've watched reruns of this show since I can remember and I don't remember this episode at all. I only came across it by watching random episodes on Hulu. I have memories of all the other episodes but for some reason not this one. It's about Carol thinking Mike is having an affair with a client, it that why it might have been skipped?

Yes, it is. The three episodes that focus on the adults are often omitted: "Mike's Horror-Scope," "Alice's September Song," and "Tell It Like It Is."

Programmers want to capture a maximal audience of children.

Quite sad isnt it?
