An old classmate from Bryant Park asks Rob (Don Grady) to be best man at his marriage. Happy to be going to Bryant Park for the first time since the Douglas family moved to California, Rob leaves the triplets with Uncle Charley (William Demarest) and Barbara (Beverly Garland) so he and Katie (Tina Cole) can attend the wedding. Rob is looking forward to seeing the old small town, and is anxious to share its charm with Katie. Little Dodie (Dawn Lyn) is looking forward to helping her mom take care of "Robbie's adorable rotten babies." Steve (Fred MacMurray) thinks Rob's going to be disappointed, believing you can never really go back home and accurately recapture the past...
"My Three Sons" ran out of steam after a healthy run, then more than doubled its television stay with gimmicks. Before you knew how the last change in situation or characters was doing, they changed again. These changes (some forced) were relaxingly paced, however. Arguably the most successful alteration in format was the pairing of Don Grady and Tina Cole (as Rob and Katie)...
Here, Rob and Katie take center stage as they "return" to the old Douglas home. We are bracketed with just the right amount of cast to make the entire production a winner. From young Gary Grimes to old Burt Mustin, the supporting cast is perfect. Chip and Ernie (Stanly and Barry Livingston) appear only in brief flashback, but it's a fine moment. Best of all is Bryant Park Hotel clerk Olan Soule (as Everett Mindermann). His inability to remember "Don" (!) Douglas is hilarious and Mr. Grady delivers one of his best late-series performances. In the end, we get to see what happened to the old Douglas home. It's all beautifully written by the prolific George Tibbles.
