David Letterman, 74

The larger-than-life personality David Letterman surely knows how to tickle our funny bones. He started as a radio jockey and also worked for the Indianapolis television station in the initial years of his career. Since David had a knack for comedy, he moved to LA to pursue his life-long dream of becoming a stand-up comedian.
We can indeed say that was the best decision the comedian made, as it’s no secret that he has a glittering career. Apart from appearing on numerous television shows, David also runs a production house and has produced several successful prime-time comedies. The septuagenarian is as equally active now as he was in his early days in tinsel town.
