Johnny began his career at age 14 with a magic act called "The Great Carsoni" in Norfolk, NE, where he grew up. As a Navy ensign aboard the USS Pennsylvania in 1945, he was the only officer to consciously entertain enlisted men during shows on the ship. While a student at the University of Nebraska, he was allowed to be late for his first class so that he could work at a local radio station, KFAB and then worked at WOW in Omaha, where he wrote comedy and announced commercials for a 15-minute program.
