As retold by Bruce Lowitt

A Chinese man and his Jewish friend are walking along one day when the Jewish man suddenly slugs the Chinese man in the mouth.

"What was that for?" the Chinese man asks.

"That was for Pearl Harbor!"

"Pearl Harbor? That was the Japanese. I'm Chinese."

"Chinese, Japanese, what's the difference?"

They continue walking in silence, then the Chinese man punches the Jew in the face.

"What's that all about?" the Jew asks.

"That was for the Titanic!"

"The Titanic? That was an iceberg."

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