Today, a nice colleague brought plenty of Krispy Kreme donuts to the office, to all our enjoyment. The one I had was a jelly-filled donut. Such a donut is called "Berliner" in southwest Germany, where I come from.
Which reminded me of John F. Kennedy's famous speech in Berlin in 1963, where he declared: All free men, wherever they may live, are citizens of Berlin, and, therefore, as a free man, I take pride in the words 'Ich bin ein Berliner!'.
So, did Kennedy tell the citizens of Berlin: "I am a jelly donut"? Not quite. In that region of Germany, this pastry is simply known as "Pfannkuchen" -- pancakes. So while certain onlookers on television might have found it funny, this humorous interpretation of the sentence went unnoticed by his local audience.
