Three guys were pulled out of detective training for special attention, because they were not very bright. The police chief was interrogating them to determine if they were smart enough to become detectives. If not, they couldn't continue with the training. Things had not gone well so far.

To test their skills in recognizing a suspect, he showed the first detective a picture for five seconds. "That is your suspect, how would you recognize him?"

The first guy answers, "That's easy, we'll catch him fast because he only has one eye!"

The Chief says, "Well...uh...that's because the picture only shows his PROFILE." Slightly flustered by this ridiculous response, the Chief flashes the picture for five seconds at the second guy and asks him, "This is your suspect, how would you recognize him?"

The second guy laughs, rolls his eyes and says, "Ha! He'd be easy to catch, he only has one ear!"

The Chief angrily responds, "What's the matter with you two? Of course only one eye and one ear are showing, it's a picture of his PROFILE! Is that the best answer you can come up with?"

Extremely frustrated at this point, he showed the picture to the third guy and in a very testy voice asks, "This is your suspect, how would you recognize him?" He quickly adds, "..think hard before giving me a stupid answer."

The guy looks at the picture intently, and says, "Hmmmm... the suspect wears contact lenses."

The Chief is surprised and speechless because he really doesn't know himself if the suspect wears contacts or not. "Well that’s an interesting answer... wait here a few minutes while I check this guy’s file and I'll get back to you on that." He leaves the room and goes to his office, checks the suspect's file in his computer, and comes back with a beaming smile on his face.

"Wow, I can't believe it... it's true! The suspect does in fact wear contacts. Good Work! How were you able to make such an astute observation?"

"That's easy," the guy replied. "How can he wear regular glasses if he only has one eye and one ear?"
