DomCom about Steven Douglas, a wise, kindly widower, raising his three sons by himself; kind of like half ''Series/TheBradyBunch''. Starred Creator/FredMacMurray and William [=DeMarest=]. The show lasted from 1960 to 1972, a total of 378 episodes in 12 seasons.

!!This show provides examples of:
%% * AnAesop
* ChuckCunninghamSyndrome: Possibly the originator of this trope, except in name. As mentioned below, Bub was no longer referred to sometime after William Frawley left; sometimes, even flashbacks showed only Uncle Charlie. Once after Mike left, it was discussed having the two younger boys move in with him, and then he was mentioned no more, neither was Ernie's being adopted. One imagines the re-marriage and Dodie would have eventually been so retconned, making Beverly Garland's character a very tired woman. Knowing of this policy, Katie's actress wondered what would happen to her if the show continued without Robbie. It only lasted one season past this, though.
* CousinOliver: Ernie (the Douglas' adopted son, joining the household in 1965), and later, Dodie (played by Dawn Lyn), as Steve's stepdaughter after he re-marries in 1969.
** In the case of the addition of Dodie, the former JumpTheShark website entry for ''My Three Sons'' had some very negative remarks about the character, eventually prompting Lyn to post her own entry sharing her positive experiences on the show and working with [=MacMurray=], Garland, Demarest and the rest of the cast.
* DistinguishedGentlemansPipe: Also SmokingIsCool. Steve smokes a pipe, and in several later episodes, Robbie also takes up pipe smoking. In addition, at least one episode showed Katie taking a job as a cigarette vendor at a nightclub (although Katie never smokes in any episode).
%% * DomCom
* LongRunner: Ran for 12 seasons (five on ABC, seven on CBS). Had it not been for faltering ratings during the final season, the possibility existed for renewal for the 1972-1973 season.
* MayDecemberRomance: Somewhat, as a 50s-something Steve begins a romance with a widowed 40-year-old woman (Barbara, played by Beverly Garland) and eventually marries her.
** This was also joked about in "Big Ol' Katie".
* MenCantKeepHouse: The men had been perfectly able to manage an all-male household before Katie joined them. When she goes away on a visit to relatives, though, now that there is a woman in the house, they've forgotten all of their housekeeping skills.
* MissingMom: Steve's first wife had died at some point before the series began, leaving him a widower with three sons. At some later point, Steve hires his father-in-law (his first wife's father), Michael "Bub" O'Casey (William Frawley), to help manage the household. The first wife's uncle, Charles ("Uncle Charlie") O'Casey, Bub's brother, takes over in 1965.
%% * PanickyExpectantFather: And grandfather.
* PantyShot: in particular, it's "I see Paris, I see France, I see Dodie's underpants!"
* ParanormalEpisode: In the episode "Coincidence." After wishing that he'd have had three girls instead of boys, Steve gives a ride to a mysterious hitchhiker visible only to himself. In a unknown neighborhood on the other side of town, Steve's car breaks down and he seeks help at a house with a widow, her mother-in-law and her three daughters - the distaff counterparts of his family, down to being the same age with similar names.
%% * ProductPlacement
* PutOnABus: At least three instances:
** Bub O'Casey, who left in early 1965 after Frawley's health began to fail. Bub was said to be on a tour of Europe, and when Frawley died in 1966, no mention was made of Bub's passing. (His replacement was Uncle Charley, played by William Demarest.)
** Mike Douglas, played by Tim Considine, who left after the first color episode of the 1965-1966 season when he grew tired of the role. He was married to his girlfriend, Sue Ann (played by Meredith [=MacRae=]), and the two moved out east ... never to return. His role was replaced by Ernie (Chip's orphaned friend, played by Stanley Livingston's real-life brother, Barry).
** Robbie Douglas, the middle son played by Don Grady, who left the show in 1971. Robbie, who followed his father into engineering, was sent to an extended construction project in Peru.
%% * SuspiciouslySimilarSubstitute
%% * ThemeTune
* TitleDrop: After the birth of Robbie and Katie's male triplets.
-->'''Robbie:''' I'm just thinking about how much I love you.....and my three sons.
* VerySpecialEpisode: Although very few of the episodes dealt with socially relevant themes, one of the final episodes -- "Whatever Happened to Ernie" -- had the Douglases helping a family of one of Ernie's classmates after it is believed that the teen had fallen into drug use.
