While it was far from one of his iconic roles, I always remember Mr. Jones' change-of-pace turn as a blind man in an episode of Frasier.
Frasier had accompanied his producer Roz to a nursing home and Jones' character overheard Frasier in the hallway, During the course of a short version, they carried on a conversation during which Frasier dropped a mask made in the shape of Jones' wife's face that had been made by Jones' daughter.
Frasier is frantically trying to glue the nose which had broken off the mask while trying to hide the fact that something is wrong from a very perceptive blind man. Finally at the end, Frasier, overcome with guilt, confesses he had dropped the mask. Jones, replies something to the effect of, so that's why you wanted my denture adhesive. I've probably dropped that mask a half-dozen times, that stuff usually works pretty well.
Rest in peace Mr. Jones.
