M*A*S*H 3: the one with Jamie Farr by RobinJRichards

Question 4

This was the NAME OF THE FILM that the US Army try to make at the 4077th as a propaganda piece. After the director abruptly leaves, Hawkeye and Trapper make their own version, channeling their inner Marx Brothers in the process (and not as "saints in surgical garb").
