An Italian, an Irishman and a black man moved out to California to seek their fortunes. The Italian and the black got jobs straight away, but weeks went by without the Irishman finding employment.
Finally, one evening he announced to his roommates that he had a big interview the next morning at nine and , setting the alarm well ahead of time, he went to bed.
In the middle of the night the other two snuck into his room, smeared his face and hands with coal dust and set the alarm forward. When it went off in the morning, the Irishman leapt from his bed, pulled on his clothes, and dashed off so as not to be late for the critical interview.
The interviewer invited him in with an apologetic expression on his face, "I'm sorry to have brought you here for nothing," the interviewer said, "but I'm afraid we simply do not employ blacks!"
"Blacks?" replied the Irishman, "What are you talking about? My name is Paddy Murphy!"
"I'm so sorry Mr. Murphy," the interviewer said, "but we simply do not make any exceptions in our hiring policy."
"But I'm not black!" shouted the Irishman.
"I'm sorry your taking it so hard." Said the interviewer, "You may think your not black, but have you looked in the mirror lately?"
The Irishman got up and went over to the mirror near the door. Staring in disbelief at his undeniably black reflection, he stammered, "Oh my God! They woke up the wrong guy!"
