"Chinese man vs Speilberg" joke

A Chinese man walks into a bar in America late one night and he sees
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 Habour, get outta here."
The astonished Chinese man
replied, "It was not the Chinese who bombed your Pearl Harbour, it was the Japanese".
"Chinese, Japanese, Taiwanese your all the same," replied Spielberg.
In return, the Chinese man 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 man, replies,
"Iceberg, Spielberg, Carsberg, you're all the same."
