Huh. I've watched some of the Simpsons episodes with commentary, and my conclusion is doing so isn't really worthwhile. It's not particularly funny or insightful, and sometimes is barely even relevant to the show being discussed. Some of the people delivering the commentary haven't watched the episode since it first aired, so you might remember more about it than they do.

Some of the Conan O'brien commentaries were funny (but still weren't particularly relevant).
