Back in 1963, JFK said "Ich bin ein Berliner" (actually "<a href="//commons.wikimedia.org/wiki/File:Kennedy_berliner.ogg" title="File:Kennedy berliner.ogg">Ish bin ein Bearleener</a>") in Berlin, and if we say "Ich bin ein Wiener", "Ich bin ein Frankfurter" or "Ich bin ein Hamburger"...? All these four words can be used for names of food.
