There was this Russian guy, this Spanish guy and this Korean guy all in the same ESL class. The teacher told them to make a sentence using the word 'hostess' for homework.
So the next day the Russian guy goes "Oh I have a good sentence. The hostess was very courteous." And the teacher said "Wow that was really good!"
The Spanish guy goes, "Oh I have a better sentence. My mother is a good hostess when others come over." Then the teacher said, "Wow that was really good!"
Finally the Korean guy goes, "I have the best sentence. When my mother answers the phone, she says hostess?"
A rabbi is sitting on an airplane next to a Korean guy. After they have been flying together in silence for a while, the rabbi leans over and says, "You know, I've never forgiven you Chinese for what you did at Pearl Harbor."
The Korean looks shocked and replies, "What the hell are you talking about?!?!? It was the Japanese the bombed Pearl Harbor, not the Chinese. And besides, I'm not Chinese or Japanese, I'm Korean!"
The rabbi says, " Korean, Japanese, Chinese, what's the difference?"
A little while later, the Korean man says, "You know, I've never forgiven you Jews for sinking the Titanic." The rabbi looks confused and mad and says, "What are you talking about? The Jews didn't have anything to do with that! An iceberg sank the Titanic!"
The Korean guy replies, "Iceberg, Goldberg, Greenberg, what's the difference?"
