I was very sad to hear this today.
In College, when we didn't have cable TV, Andy Griffith, and MASH were my bread and butter. I love those shows dearly, and AG always made me feel better when I was down.
RIP Andy Griffith.
On a facetious note, Don Knotts died in 2006, George Lindsey (Goober) died in May, Andy Griffith just passed. . . is Ron Howard next!?
The Andy Griffith Show was a staple of my childhood, and I'm not embarrassed to admit that I enjoyed a Matlock or two as well. Andy was also excellent in various other appearances.
If you never saw him play a heavy, you might have assumed that he always played the folksy, white-bread good guy, but that wasn't all he could do. Sure he got a bit typecast, but that's a testament to how good he was in those iconic roles. But he could bring the nasty.
