A policeman was interrogating 3 blondes who were training to become detectives. To test their skills in recognizing a suspect the shows them a picture then quickly hides it.

The asks “This is your suspect, how do you recognize him?”
The 1st woman replies “that’s easy; we’ll catch him fast because he only has one eye.”
The policeman replies “Well, uh, that’s because the picture shows his profile

Slightly frustrated, he quickly flashes the picture at the second woman and asks ‘ this is your suspect, ho would you recognize him?”
She replies “he’d be too easy to catch because he only has one ear.”

The policeman angrily responds “what’s the matter with you two? Of course he only has one eye and one ear because it’s his profile!”

Now he’s furious and flashes the picture at the 3rd women and says “think really hard before you give me a stupid answer, this is your suspect how would you recognize him?’

She replies “the suspect wears contact lenses.”

 
The officer is dumbfounded and leaves to check the suspects file. He returns and says “Wow!” It’s true.
How were you able to make such an observation?”

She replies…

“It’s was easy! He can’t wear glasses because he only has one eye and one ear!
