After Leon Schlesinger told them not to use the fat version of Porky Pig anymore, Tex Avery and Bob Clampett discussed with each other the fact that they found Arthur Q. Bryan’s (himself a heavy man) performance funnier when he recorded them than when they were synched with Elmer. So the two directors redesigned Elmer to resemble Bryan. After a few more cartoons, Clampett decided that the redesign had been a mistake and reverted Elmer to his previous, classic form.
