Tone: Clever

A police officer is interviewing three recruits who are training to become detectives.

To test their observational skills, he shows the first recruit a photograph of a suspect for five seconds before hiding it.

“This is your suspect,” he says. “How would you recognize him?”

The first recruit answers, “Easy. We’d catch him right away because he only has one eye.”

The officer sighs. “That’s because I showed you his side profile.”

Trying again, he shows the same photo to the second recruit for five seconds. “This is your suspect. How would you recognize him?”

The second recruit smiles confidently. “Even easier. He only has one ear.”

Now the officer is furious. “What’s wrong with you two? Of course he only has one eye and one ear. It’s a side-profile photo! Can’t either of you come up with a better answer?”

Completely exasperated, he turns to the third recruit. “This is your suspect. How would you recognize him?” Then he adds, “And think carefully before you give me another ridiculous answer.”

The third recruit studies the photo for a moment. “The suspect wears contact lenses.”

The officer blinks in surprise. He doesn’t actually know whether the suspect wears contacts.

“That’s… an interesting observation. Wait here while I check his file.”

A few minutes later, the officer returns with a huge smile. “Incredible! You’re right. The suspect really does wear contact lenses. How on earth did you figure that out?”

“Simple,” the third recruit replies. “He can’t wear regular glasses because he only has one eye and one ear.”
