英语幽默笑话：What Color什么颜色

An impoverished graduate student at Clemson University in South Carolina, I was excited when my father informed me that he had bought me a car. Hardly able to contain my enthusiasm, I asked Dad the typical questions: "What kind is it? Does it have a stick shift? Does it have a tape deck?"　　
"It's a 1982 Toyota," he replied. "It's a four speed, and, yes, it has a tape deck . " Pleased, I asked what color it was. 　　
"Well, " he said uncomfortably, " which part?"

作为南卡罗莱那州克莱姆森大学的一个本科生，我囊中羞涩，当我父亲告诉我他为我买了辆车时，我甚是激动。我几乎控制不住我的热情，问了爸爸几个关键问题：“什么车？有没有手排挡？有没有磁带舱？”
“是1982年产丰田车，”他回答说，“四速，还有，是的，有磁带舱。”我甚是高兴，又问是什么颜色的。
“哦，”他很不舒服地说，“你指哪一部分？”
