Sadly, Dave was born without ears, and  though he proved to be successful in business, his problem annoyed him greatly.  One day he needed to hire a new manager for  his company, so he set up three interviews.
The first guy was great. He knew everything he needed to know and was very interesting.  But at the end of the interview, Dave asked  him, "Do you notice anything different about me?"
"Why, yes, I couldn't help but notice that you have no  ears," came the reply.
Dave did not appreciate his candor and threw him out of the office.
The second  interview was with a woman, and she was even better than the first guy.  But he asked her the same question:  "Do you notice anything different about me?"
"Well," she said stammering, "you have no ears."
Dave again got upset and chucked her out in a rage.
The third and final interviewee was the best of the bunch, he was a young man who had  recently earned his MBA.  He was smart. He was handsome, and he seemed to be a better businessman than the first two put together.  Dave was anxious, but went ahead and asked the young man the same question: "Do you notice anything different about me?"
Much to his surprise, the young man  answered, "Yes, you wear contact lenses, don't you?"
Dave was shocked and realized this was an incredibly observant person.
"How in the world  did you know that?", he asked.
The young man fell off his chair laughing hysterically and replied,
"Well, it's pretty hard to wear glasses with no fucking ears!"
