TV.Com - The Dick Van Dyke Show (http://www.tv.com/the-dick-van-dyke-show/show/535/episode_listings.html)
I agree with the rating of 9.1 for "The Curious Thing About Women." It's always been my altime favorite episode, and I'm glad to see it rated so highly :) . However, "The Two Faces Of Rob" was rated even higher; 9.3, and I didn't like it quite as much, personally :( .

That used to be TVTome.com. I went back to check how I rated those episodes, and I gave them both a 10. I tend to be very generous when rating episodes of my favorite shows there.
