One Job & three Applicants

There were three applicants for one job that required
"The Powers of Obvervation & Attention to Detail"
The first applicant enters the interviewers office & is told
"the job requires the powers of observation & attention to
detail - What do you notice different about me"
He responds by commenting "You have no freaken ears"
The interviewer says "Please leave as I am very sensitive about
that
& send in #2."
#2 enters & is posed the same job description "the job requires
attention to detail & the powers of observation - What do you
notice different about me?"
The applicant responds & says "you have no freaken ears"
The interviewer again says "Please leave as I am very sensitive
about that & send in #3."
But before #3 goes in for his interview the other two warn him
not to mention the interviewers ears because he is very
sensitive about that.
#3 enters & is told that the job requires the powers of
observation & attention to detail & is asked "What do notice
different about me?"
He responds by saying the the interviewer is wearing Contact
Lenses.
The interviewer says that is correct & how did he come to that
conclusion.
Applicant #3 says you can't wear glasses you got NO FREAKEN EARS.
