What cartoon character from the 1970s said, "It will never work"?

"Musical Director Carl W. Stalling's name appears in a newspaper article Elmer Fudd reads at the beginning of this cartoon. The headline reads, "Smellevision Replaces Television" followed by the byline, "Carl Stalling sez, 'It Will Never Work!"

I believe it was Rocky from Rocky & Bullwinkle.

This is from memory. Hard to find a reference on this, but this is the best I could do.

"Even in its first episode, the familiar gags were all present. Bullwinkle tries to pull a rabbit out of his hat, Rocky scolds him, saying it will never work..."

Could it be Hardy Har Har the Hyena from "Lippy the lion and Hardy Har Har"? hard to find a direct quote but I remember he had very little positive to say - probably with good reason!

"Lippy was, as the name implies, a lion; and Hardy was a rather dour-faced, non-laughing hyena. Their schtick was that Lippy would come up with a wonderful but unworkable scheme to achieve whatever goal he was after; but it was usually Hardy, the pessimistic one, who suffered worse from whatever consequences befell them as a result"
