They were treated so brutally that they could really find no humor there.
One humorous story though was the enterprising young man from NM who realized that getting VD was one of the most shameful things that could happen to a Japanese soldier. He carved a pill press and made plaster of paris “penicillin” pills and helped keep a lot of people alive with the food he traded for, I just always think what a sweet revenge he felt too.
I know, but I was making a Hogan’s Hero reference..
