A couple of thoughts, both about the same character.
When John Banner was offered the Sgt Schultz role he was reluctant to take it. He was Jewish. When it was pointed out that he'd actually be lampooning the Germans he agreed and made his character as part of pop culture. Everybody knows about the Schultz solution to problems: "I see nothing. I hear nothing." It's a necessary part of every politician's repertoire.
More comically, my next door neighbour had been in the Luftwaffe during WWII. At 6'5" tall and weight in at around 330 lbs, he looked like a giant-sized John Banner. He never missed a show because he liked seeing himself on screen. He didn't have the intelligence to know that he was being mocked.
I just realised that I forgot to answer your question. No, I don't think it's bizarre.
