Writers often are inspired and creative people and those for this show are no different. We know that Klinger was in the Army and there was a time when he was trying to get thrown out. Naturally, he worn women’s clothing as his attempt to be disqualified.
That idea came from Lenny Bruce. Bruce was given a dishonorable discharge from the Navy for an identical reason. To those in the Military, this is not a practice that is advised. If you commit to serving the country and end up with cold feet, you are better off finishing out your contract before you try and leave. A dishonorable discharge is not good.
Based on a Book
Richard Hooker, the author of the novel MASH: A Novel About Three Army Doctors, is the reason the beloved show was even created. After serving in the military, he wrote his novel based on his time in the Korean War. In a matter of four years after it was published, the TV show was created.
He wrote two more novels that following this big success. But of course, this was the one that drew the most attention as it had enough meat on its bones for writers to create 11 entire TV show seasons out of it. There must have been something about the novel that made the creators want to pick it up and turn it into a series. Great writing, Hooker.
