I read on the blog Stuff Dutch People Like that Number 23 is jokes about the Germans. Here's one I heard over the weekend on television.
A couple adopt a fair haired boy from Germany, happy with the latest addition. He seems the perfect baby. He never cries or complains. But as the months become years, the couple worries because the boy doesn't speak. They take him to doctors who run a battery of tests, the results revealing nothing but good health.
Then when the boy is around four, following a family dinnner, he looks at his adoptive parents and says, "This strudel is a bit tepid."
His parents are overjoyed at the sound of his words. They don't care their son speaks with a German accent. "Wolfgang," they yelp, "Why have you taken so long to speak?"
"Because everything so far has been quite satisfactory..."
