A Jew in Japan
Joke: A Jewish American is in Tokyo, Japan on business. He is riding around the Ginza in a taxi when he suddenly realizes it's Friday night.
He asks the cab driver if there's a Jewish synagogue in Tokyo and the driver takes him to an unmarked building. The American enters and is surprised to find a Japanese-Jewish congregation with a Japanese-Jewish rabbi.
They are all wearing yarmukas (skull caps) and talaysim (prayer shawls). He participates in the service which is in Hebrew -- the international Jewish language for prayer. At the end of the service, the rabbi walks up the aisle and spots the American. He approaches and says with his thick Japanese accent, "You ... Jewish?"
The American replies, "Why yes I am".
The rabbi looks at the American and says, "Funny... you no looka Jewish".
