You may have to dip pretty far back into the recesses of your TV memory to recall "My Three Sons," a sitcom about a widower (Fred MacMurray) raising a trio of boys (hence the name) as a single dad. Well, not entirely single. He had some help from his father-in-law during the first few years of the show, then from housekeeper Uncle Charlie. (A male housekeeper? Kinda forward-thinking for a show that ran during the '60s and early '70s.) 
In one of the many storyline changes that occurred during the comedy's run, MacMurray decided to adopt a friend of his son Chip's after the boy's parents died in a car accident. The kid's name was Ernie and he was cute, a little nerdy and an obvious attempt to keep the three sons concept alive after the eldest, Mike, was written out of the show. Ernie Douglas was played by Barry Livingston, who happened to be the real-life brother of Steve Livingston, the actor who played Chip. After "My Three Sons" ended its run in 1972, what became of the boy we knew and loved as Ernie?
This is one of those Rich or Rehab stories that doesn't quite have a twist ending. As it turns out, Livingston kept on acting. His resume, seen here on imdb, is pretty long, filled to the brim with TV credits on shows such as "Ironside," "Hart to Hart," "Doogie Howser" and "Ally McBeal." You even may have seen him more recently on "Mad Men" and "Two and a Half Men," or in the movie "You Don't Mess With the Zohan."
Livingston, who turns 55 later this year, is also married and the
father of two children. Okay, so he doesn't have three sons. But it
looks like the guy is doing pretty well for himself. Uncle Charlie
would be proud. Here is what Livingston looks like now:

And, for old time's sake, here is the opening of "My Three Sons." Enjoy.
