Although Los Angeles native Howard McNear had a long career on radio and in films, he will forever be remembered for his memorable - and scene-stealing - portrayal of Floyd the Barber in the long-running The Andy Griffith Show (1960) (actor Don Knotts once said that playing Floyd wasn't much of a stretch for McNear, as his real personality was pretty much like Floyd to begin with).

Interesting that he played a barber in BOTH ...

"Andy" the barber on LITB, I believe.

Hard to imagine him as "Doc" on Gunsmoke.

He also had a later-season run on the Burns and Allen show, as Jantzen the plumber in 10 episodes. He was Gracie's 'counterpart' -- he was as goofy on the show as she was.

The Beaver appearance was single-shot--yes, Andy the barber. Ward rigged a fake shave for Wally, to make up for embarrassing him in front of Eddie, at home.

Finding a show from that era that he didn't apper in would be a challenge.
