A policeman was interrogating 3 guys who were training to become detectives.

To test their skills in recognizing a suspect, he shows the first guys a picture for 5 seconds and then hides it. “This 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 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 guy and asks him, “This is your suspect, how would you recognize him?”
The second guy smiles, flips his hair, and says, “Ha! He’d be too easy to catch because he only has one ear!”
