An old Jewish man walks into a bar and sits down.
He has a few drinks, looks around him and suddenly freezes when he sees a Chinese man. He gets up and punches him in the face.
"Ouch!" the Chinese man cries, holding his nose. "What was that for?"
"That was for Pearl Harbor!" the Jewish man says.
"But I'm Chinese!"
"Chinese, Japanese, what's the difference?" Growls the old man as he turns and sits back down.
A few seconds later, the Chinese man walks up to the Jewish man and punches him in the face.
"Ouch!" the Jewish man cries, holding his nose. "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?"
