Name this cartoon/ comic book character

Okay here’s what I remember:
The character wore a kind of turtleneck shirt. The collar was stiff and turned up so that you never saw the lower half of his face. I believe the idea was that he was deformed in some way. I seem to vaugely recall one scene where he’s pulling the collar away from his face with one hand and stuffing food in his mouth with the other. This was done in such a way so that you nevr saw the lower part of his face. There may have been another scene where his back is to the viewer and the collar has slipped or come loose and everbody is recoiling in disgust.

Mort from Bazooka Joe?
