Neither an Oscar or an Emmy. That I can think of, that just leaves a Tony, but why a Tony winner would be best known for work on TV eludes me…
Okay, too be perfectly clear, he worked in radio and his work appeared in movie theaters, and the movie-theater work has been shown repeatedly on TV from the 1950’s until, well, possibly today. He also did a good deal of TV work as well.
Well, that explanation certainly didn’t help me any…
IQ: Was he known for his talent, or lack thereof, on the violin?
Good one, etv, that could be it. Hmm. How about these:
IQs:
Were you Fifties TV’s beloved “Uncle Miltie”?
Did Ronald Reagan claim for several years to be reading a book you wrote?

Take another DQ for the second.

George Burns.
DQ:

Two DQs reserved. Any other suggestions?

DQ18) At peak of popularity before 1970.
Not George Burns, eh?
Nope, not George Burns. See post 107.
D’oh! Missed that. Thanks.
Still can’t figure out who this dude is.
Well, do you guys want to use a few more DQs or throw in the towel?
Hmm. Maybe this will help:

Wait a minute…
IQ:Is the epitaph on your tombstone “That’s all folks”, a frequent catchphrase in your best known work ?
(I think this one meets all the DQs so far)
Good on Heady!
Or maybe: IQ: Were you married to Lovie, while also known as a blind man who narrowly avoids disaster?
Ehhh, What’s Up, Chock? 
Yes! I am MEL BLANC, Man of 1,000 Voices!
I’ll let the Dopers explain his vast range:

Just for the record: Mel Blanc played Barney Rubble on all six seasons of The Flintstones on TV; was the winner of the prestigious Windsor McCay Award for lifetime achievement in animation; and was the first voice actor ever to be given individual credit in a cartoon or film!
Well done, ChockFull! All hail!
Good thought, but obviously I’m not Jim Backus.
