Change the Names

One guy says to another guy, "Mandelbaum and Rosenstern were talking one day..."

Right away, his friend interrupts him, "Always with the Jewish jokes! Give it a rest! Why do they always have to be about Jews? Just change the names to another ethnic group for once!"

So he starts again, "Hashimoto and Suzuki were talking one day at their nephew's Bar Mitzvah..."
