This is a "BEST JOKE" award winner in UK, apparently

One Chinese person walks into a bar in America late one night and he saw Steven Spielberg. As he was a great fan of his movies, he rushes over to him, and asks for his autograph.

Instead, Spielberg gives him a slap and says "You Chinese people bombed our Pearl Harbor, get out of here."

The astonished Chinese man replied "It was not the Chinese who bombed your Pearl Harbor , it was the Japanese". "Chinese, Japanese, Taiwanese, you're all the same," replied Spielberg.

In return, the Chinese gives Spielberg a slap and says "You sank the Titanic; my forefathers were on that ship."

Shocked, Spielberg replies "It was the iceberg that sank the ship, not me." The Chinese replies, "Iceberg, Spielberg, Carlsberg, you're all the same."
