Heard this joke on BBC radio many years ago and it still makes me laugh.
An American Jew and a Chinaman are getting increasingly drunk at a bar. After a while the Jew goes up to the Chinaman, hits him in the face and knocks him off his stool.
Chinaman: Ahh, what you do dat for?
Jew: Pearl harbour
Chinaman: But I Chinese not Japanese
Jew: Pah, Chinese, Japanese they're all the same to me
A little while later the Chinaman goes up to the Jew and delivers a solid right hook that leaves the Jew on the floor.
Jew: Man, what ya playing at!
Chinaman: That for Titanic
Chinaman: Goldberg, Iceberg it's all the same to me.
