In "The Late Captain Pierce" Klinger says "General Eisenhower," but in the second half Hawkeye says "What's he coming over here for anyway? Who needs a president with dysentry?" Eisenhower wasn't inaugrated until January 1953, and the episode was taking place before the end of 1952!!

yes, there's MANY, MANY goofs like that throughout the series. Like, in one episode Hawkeye sings a line from the theme to "The Mickey Mouse Club". But that didn't start until 1954-whis was after the Korean war.
Also, the "Godzilla" and "Bonzo" movies are frequently mentioned-but both series didn't start until, again, AFTER the Korean war.
But, the most jarring goof has to be the one in the episode "Movie Tonight" from season 6. In one scene, Radar does an impression of John Wayne, in a scene from the movie "McClintock"-which came out in (ready?)-1963!!!!!! :lol:

Treky, Radar is psychic!
