Rob: (To Mr. Peters) Why didn't you tell me on the phone?
Rob: Say, guys, don't you want to see the baby?
Buddy: Of course we want to see the baby. I've been practicing funny faces all day.
Sally: The one you're doing now is hysterical.
According to the title shown in the episode, the actual title of this episode is That's My Boy??, and not That's My Boy???.
I made a mistake and would like to correct it, the list was "MOST" memorable TV Moments, sorry.
Greg Morris arriving to prove Rob brought home the correct baby was named #90 on TV Guide / TV Lands "100 Most Memorable TV Moments" in December of 2004.
The script for this episode was published as 'That's My Boy??'—A Milestone in Television History" in The Dick Van Dyke Show: Anatomy of a Classic by Ginny Weissman and Coyne Steven Sanders. New York: St. Martin's Press, 1983 (129–38).
Rob stores the baby's records in a copy of The Magic Mountain, the classic novel by Thomas Mann.
