A policeman was testing 3 brothers who were training to become detectives.
To test their skills in recognizing a suspect, he shows the first brother a picture for 5 seconds and then hides it. “This is your suspect, how would you recognize him?”
The first brother answers, “That’s easy, we’ll catch him fast because he only has one eye!” The policeman says, “Well…uh… that’s because the picture I showed is his side profile.”
Slightly flustered by this ridiculous response, he flashes the picture for 5 seconds at the second brother and asks him, “This is your suspect, how would you recognize him?”
The second brother smiles and says, “Ha! 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 only one eye and one ear are showing because it’s a picture of his side profile! Is that the best answer you can come up with?”
Extremely frustrated at this point, he shows the picture to the third brother and in a very hasty voice asks, “This is your suspect, how would you recognize him?
He quickly adds, “Think hard before giving me a stupid answer.”
The brother looks at the picture intently for a moment and says, “The suspect wears contact lenses.” The policeman 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 for a few minutes while I check his 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 contact lenses. Good work! How were you able to make such an astute observation?”
“That’s easy,” the third brother replied. “He can’t wear regular glasses because he only has one eye and one ear.”
