Well....ahem:

Berliners don`t call Berliners Berliners. Only non-Berliners do.

Just to make it more clearly:

The inhabitants of Berlin don`t call jelly doughnuts "Berliner". They call them "Pfannkuchen" which means "pancakes". Which is of course quite different from a jelly doughnut.

Pretty confusing, isn`t it?
