Don Rickles
Often called the best insult comedian in the country, Don Rickles chanced upon his first job in 1941 just after completing high-school. It was that of a seaman in the US Navy, which allowed him to serve on the USS Cyrene for nearly five years.
After getting discharged from service, he enrolled himself into the American Academy of Dramatic Arts before the world of stand-up comedy opened the doors for him. By this time, Rickles knew what he wanted to do and ended up entertaining people with his wit for the remainder of his lifetime.
