From what I understand, Klinger and his Korean wife relocated to the States in AfterMASH, where he proceeded to behave like a low-rent Ralph Kramden clone, all "No wife o' mines gonna get a job!"
I grew up not knowing that Radar O'Reilly wasn't actually my grandfather, because I had a picture of him from the Korean war and it looked exactly like the same person.
I also had difficulties with Jesus and Abraham Lincoln.
