Three blondes were applying for the last position with the Texas Highway Patrol.
The interviewing detective said, "So y'all want to be cops?" They all nodded.
He opened a file drawer, pulled out a folder, and took out a photograph. "To be a detective, you must be able to detect," he explained. "You need to notice distinguishing features and oddities." He then showed the photo to the first blonde for just two seconds.
"Did you notice any distinguishing features about this man?" he asked.
"Yes," she replied immediately. "He has only one eye!"
The detective shook his head. "Of course he has only one eye in this picture! It's a profile shot! You're dismissed!" The first blonde left.
He then showed the photo to the second blonde for two seconds. "What about you? Notice anything unusual?"
"Yes! He only has one ear!"
The detective put his head in his hands. "Didn't you hear what I just said? This is a profile! Of course you only see one ear! You're excused too!" The second blonde left sheepishly.
Finally, he turned to the third blonde. "This is probably a waste of time, but..." He flashed the photo briefly. "Alright, did you notice anything unusual?"
"I sure did," she said. "This man wears contact lenses."
The detective frowned, looked at the picture again, and checked the papers in the folder. He looked up, puzzled. "You're absolutely right! His bio says he wears contacts! How could you tell from his picture?"
The blonde rolled her eyes and said, "Well, hello! With only one eye and one ear, he certainly can't wear glasses."
