Pat Sajak
The longest service of Sajak’s career has been on the show Wheel of Fortune, but he once served his country in Vietnam. Sajak was in the U.S. Army. He trained as a clerk typist but took a posting in Saigon as a disk jockey. Sajak may not have carried a gun on the front lines, but he reached the ears of many service people at the time, raising their morale with every broadcast.
