Three guys

Three guys walk into a room for a job interview. The man that is giving the
interview has no ears. When the first man is called in the interviewer says,
"This job is going to require observations. Make an observation about me." So
the man says, "You don't have any ears." The interviewer say, "GET OUT!" Then
the second man walks in and the same thing happens. When the third guy makes his
observation he says, "you wear contacts." The interviewer says, "WOW! How did
you know?" "Because you don't have any ears to hold up your glasses."
