I am trying to find a performer who sounds like Charlie in the Box from Rudolph, the Red-Nosed Reindeer (1964).
I think it was a male and he was on some old B&W sitcom or in an old B&W comedy movie. The character played was always whining and complaining about how difficult everything was.
It is not the actor, Alfie Scopp, who did the voice for Charlie. I checked his IMDB and have not seen anything he did other than Rudolph.
The clip is from youtube showing Charlie about 10 seconds in.
