A false fact that has been written in several Marine Corps books is that Don Knotts was a Drill Instructor in the United States Marine Corps. Don does not know how this rumor got stated. It embarrasses him because; he does not think he could have made it through Marine Corps booth camp. For the record he would like people to know that he did service this country but not with the Marines. When he was 19 he joined the army. This is when he got his start in show business. His duties consisted of entertaining the troops. He was in traveling GI variety shows called "Stars and Gripes."
