A man had just boarded the plane and settled into his seat next to the window, when another man sat down in the aisle seat, and proceeded to put his black labrador in the middle seat next to the man.
The first man looked very quizzically at the dog and asked the second man why the dog was allowed on the plane.
The second man explained that he was from the Police Drugs Enforcement Agency and that the dog was a ‘sniffing dog’.
“His name is Sniffer and he’s the best there is”, the policeman said. “I’ll show you once we get airborne, when I put him to work”.
So, the plane took off, and once it has leveled out and the seatbelt sign was turned off, the policeman said, “Watch this”.
He told Sniffer to “Search”.
Immediately, the black labrador jumped down, walked along the aisle, and finally sat very purposefully next to a woman for several seconds. Sniffer then returned to his seat and put one paw on the policeman’s arm.
The policeman said, “Good boy”.
He then turned to the man and said, “That woman is in possession of marijuana. I’m making a note of her seat number and the authorities will apprehend her when we land”.
“Wow, that’s impressive”, replied the first man.
Once again, the policeman sent Sniffer to search the aisles.
The black labrador sniffed about, then sat down beside a man for a few seconds, returned to its seat, and this time he placed two paws on the agent’s arm.
The policeman said to the man sitting next to him, “Two paws mean that man is carrying cocaine, so again, I’m making a note of his seat number for the police.”
“I like it!” said the first man.
Once again the policeman told Sniffer to “Search”.
The black labrador walked up and down the aisles for a little while, sat down for a moment, and then came racing back to the agent, jumped into the middle seat and proceeded to crap all over the place.
The first man was really disgusted by this behavior and couldn’t figure out how or why a well-trained dog would behave like that.
So he asked the policeman, “What’s going on?”
The policeman nervously replied, “He’s just found a bomb”.
