As You Were (trivia)
Radar O'Reilly states his age to be 19 in this episode. Gary Burghoff, who plays Radar, was 30 when this episode was filmed.
Henry was not always the brightest bulb of the bunch. During his lecture he talks about being 20,000 miles from home. As the world is divided into 24 time zones, each one approximately 1,000 miles or so, one could not have been more than about 12,000 miles from home, maybe a bit farther depending on latitude positioning I suppose.
