David Letterman was born in Indianapolis to a father who was a florist and a mother who was a church secretary. As a young boy, Letterman admired his father's ability to craft jokes. The youngster was able to put his own jokes to the test when he became a radio host for his college's student-run station and eventually as an anchor and weatherman on a local Indianapolis television station.
