Best joke in Britain

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."
