Whats the difference?

A Jewish man walks into a bar and sits down. He
has a few drinks, then he sees a chinese man and
punches him in the face. "Owch!" the chinese man
says. "What was that for?" "That was for Pearl
Harbor," the Jewish man says. "But I'm Chinese!"
"Chinese, Japanese, what's the difference?"

And the jewish man sits back down. Then, the
chinese man walks up to the Jewish man and
punches him in the face. "Ouch!" the Jewish man
says. "What was that for?" "That was for the
Titanic," the chinese man says. "But that was an
iceberg!"

"Ice berg, Goldberg, what's the difference?"
