The BBC seems to have forgotten that in past times of crisis it successfully weaponised humour against a threat from a very nasty regime in Germany. It was very effective to, serving to keep morale high even when invasion looked likely.
Were a similar regime to emerge now, the BBC would be instructing comedians and script writers to avoid jokes about uniforms, cooking with gas, Germans having no sense of humour as they might offend Germans or people of German descent living in Britain.
Here’s an WW2 joke example my Dad told me years ago. Bear in mind attitudes to bad language are a lot more relaxed now:
A World War II pilot is reminiscing before school children about his days in the air force. “In 1942,” he says, “the situation was really tough.
The Germans had a very strong air force. I remember, “ he continues, “one day I was protecting the bombers and suddenly, out of the clouds, these fokkers appeared. (At this point, several of the children giggle.) I looked up, and right above me was one of them.
I aimed at him and shot him down. They were swarming. I immediately realized that there was another fokker behind me.”
At this instant the girls in the auditorium start to giggle and boys start to laugh. The teacher stands up and says, “I think I should point out that ‘Fokker’ was the name of the German-Dutch aircraft company”.
“That’s true,” says the pilot, “but these fokkers were flying Messerschmidts.”
