It's typical part of the german language. As a male you say the name of the town and ending a -er (a woman ending -erin) to the tolwn you come from.

So also whe can say: "I am a Hamburger", "a Nuernberger, a Frankfurte, a Wiener" (kind of sausages) - like anything, where food and town are the same...

jokey? Yep.

But this speech of JFK was the answer to occupie Berlin instead of cuba.

"...Aachen Stadt I does not endorse the politics of the Nazi party; in fact they say right up front that they will not tolerate racist ideology..."

Don't believe it! In election 1933 there were more than a quarter for hitler, after then there was no chance to fight against the Nazi's. The last jews were deported in 1942. No racism?
Between 1934 and 1945 they were all silent or Nazi's, and it's easy to say they weren't.
