Reminds me of a story...

Two guys are sitting in a bar. One is Chinese, the other Jewish. Suddenly the Jewish guy jumps up and slugs the Chinese guy in the face. Picking himself up off the floor, the Chinese guy says, “Why’d you hit me?”
The Jewish guy replies, “That was for what your people did at Pearl Harbor.”
The other fellow says, “But that was the Japanese, not the Chinese!”
“What’s the difference?, answers the first.
Another few beers go down in total silence. Then the Chinese guy stands up and hits the Jewish guy with a barstool.
“What was that for?” says the Jewish guy, rubbing his head.
“That was for what your people did to the Titanic,” says the other fellow.
“But the Titanic was sunk by an iceberg!” said the Jewish guy.
“Iceberg, Weinberg, Goldberg, what’s the difference?” answers the Chinese guy.
