MASH had a "5 O'clock Charlie" episode as well.
Season 2 Episode 2
Every day for the past six weeks, at 5:00 o'clock p.m. on the nose, a North Korean "washout from Kamikaze school" has let loose a bomb in the general direction of the hospital's sub-ammo dump. Very affectionately known as "Five O'Clock Charlie," the only thing he hits on the nose is the time.
Yeah. And so did black sheep squadron.
The real washing machine Charly was over the South Pacific. There was a bedcheck charley, a German who flew over US forces in Europe , doing the same sort of thing.
There may have been one over Korea. The leftist tv show mash did make up a bunch of crap. Can’t tell the real from the propaganda.
