A commissioner was interviewing 3 ex pongos who were training to become policemen.
To test their skills in recognising a suspect, he shows the first a picture for 5 seconds and then hides it.
“This is your suspect, how would you recognise him?”
The first ex pongo answers, “That’s easy, we’ll catch him fast because he only has one eye!”
The commissioner 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 and asks, “This is your suspect, how would you recognise him?”
The second ex pongo says, “Ha! He’d be too easy to catch because he only has one ear!”
The commissioner angrily responds, “For God’s sake, What’s the matter with you two?? Of course only one eye and one ear are SHOWING because it’s a picture of his profile!! Is that the best answer you can come up with?!?”
Extremely frustrated at this point, he shows the picture to the third ex pongo and in a very testy voice asks, “Now think hard before giving me a stupid answer. This is your suspect, how would you recognise him??”
The ex pongo looks at the picture intently for a moment and says, “Hmmmm…the suspect wears contact lenses…”
The commissioner is surprised and speechless… “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,” replied the ex pongo. “He can’t wear regular glasses because he only has one eye and one ear…”
