Sammy Davis Jr. in a 1955 appearance on What’s My Line? If you’re wondering about the eyepatch, this is apparently shortly after the car accident that cost him his eye (as made evident later in the clip). Later appearances he would have a glass eye. Like most times we’ve looked at this show, I’m terribly amused by the voices the guest uses to disguise their own. Davis pulls out several.
