"Chinese and Jew student drinking too much" joke

There were two good friends (roommates, actually) at a University. One of them was a Chinese and the other was a Jew.
One day they went drinking and had a little too much. Upon staggering back home, they got into some stupid mindless argument. One thing led to another and suddenly the Jewish guy was pummeling the Chinese. Finally, exhausted, the Jewish guy stopped.
The Chinese, black eyes and all, opened one eye with some effort and asked him, "Why did you beat me"?
The Jewish guy replied, "That was for Pearl Harbour".
"But they were Japanese,..." exclaimed the Chinese.
"Japanese, Chinese, all the same thing", replied the Jewish guy.
Some time went by. Again they went drinking and had a little too much. Once again there was the crazy mindless argument. They broke into a fight as soon as they reached home. This time the Chinese guy had the upper hand and almost did the Jewish guy in.
Finally, winded, the Chinese guy has to stop. The Jewish guy opens one eye and asks, "What was that in aid of?"
The Chinese guy replies, "That was for the Titanic".
Incredulous, the Jewish guy says, "But the Titanic was downed by an iceberg!"
The Chinese guy replies, "Iceberg, Goldberg, all the same thing..."
