Incidentally, among the 3rd season episodes on Youtube is "Lt Preston of the 4th Calvary," the episode CBS refused to air because of the (in retrospect, very innocent) bedroom scene with Dick and Jenny, and with their daughter, Annie, who catches them in action. When CBS would not air the episode, Carl Reiner was angered and vowed quit as producer. Dick Van Dyke subsequently announced he would quit because he did not want to continue the show without Carl Reiner. However, it's questionable whether the show would have gone on anyway because Hope Lange, a couple months earlier, had announced she would not return to the show for a fourth season (she was disenchanted with her underutilization on the show and her three-year contract was ending), and the show was in 40th place that season, so CBS might not have been willing to renew anyway. CBS had a three-year agreement with Dick Van Dyke, and their commitment was now over.

I just watched "Lt. Preston of the 4th Cavalry." Now I understand why Carl Reiner was so furious that CBS refused to air it. It's very funny.
