Varney portrayed the rubbernecked rube "Ernest" in a series of movies and hundreds of TV commercials.
In the commercials, he got his fingers slammed in a house window, fell off a ladder and got electrically shocked fooling with a broken TV set. He plugged a variety of sponsors, including dairy products, car dealerships, pizza and radio stations.
He said in 1984, "Ernest is a neighbor or relative that we've all had at one time. He's abrasive, but he doesn't mean to be. He gets excited and ends up standing on your toes. I try to make him clownish and I don't want him too low key; and he's physically funny."
"It's been my biggest sounding board. I've grown to know him well."
He laughed when asked if he's anything like Ernest.
"Am I a bozo? I'm not abrasive. But yes, I guess I am a bozo."
Varney, born and raised in Lexington, Ky., first gained attention as a standup comic, performing at The Comedy Store in Los Angeles.
Varney told reporters he suffered from depression much of his adult life.
A memorial service will be scheduled in Nashville and Varney will be buried in his hometown of Lexington.
