King began his comedy career with one-liner routines and other material concerning mothers-in-law and Jews. His style of comedy changed when he saw Danny Thomas performing in the early 1950s. King realized that Thomas was talking to his audience, not at them, and was getting a better response. King changed his own style from one-liners to a more conversational style that used everyday life for humor. His comedy inspired other comedians such as Joan Rivers, Jerry Seinfeld, Larry David, Billy Crystal, Robert Klein, and Bill Cosby.
