I know there has to be a number of broadcast bloopers to MASH. I have heard of the one where Hawkeye was wearing current day blue sneakers at one time. I just recently saw one of the cook walking through a line of people and he had his script book open as came through. In a split second the same scene showed again but this that time he did not have his script book with him. I noticed it in the episode when Hawk and BJ were morale officers.
