A Jewish man and a Chinese man are in a bar. Suddenly, the Jewish man punches the Chinese man in the face.

"Ow! Why did you do that?" asks he Chinese man.

"That's for Pearl Harbor," says the Jewish man.

"But the Japanese bombed Pearl Harbor. I'm Chinese!" says the Chinese man.

"Chinese, Japanese, what's the difference?" asks the Jewish man.

So the Chinese man punches the Jewish man.

"Ow! What's that for?" asks the Jewish man.

"It's for the Titanic," says the Chinese man.

"What? That was an iceberg that brought down the Titanic!" says the Jewish man.

"Iceberg, Goldberg, what's the difference?"
