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

To test their skills in recognizing a suspect, he shows the first blonde a picture for 5 second and then hides it. "This is your suspect, how would you recognize him?"
The first blonde 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 shows his profile."
Slightly flustered by this ridiculous response, he flashes the picture for 5 seconds at the second blonde and asks her, "This is your suspect, how would you recognize him?"
