A man is sitting in an airliner, which is about to take off when another
man with a Labrador Retriever occupies the empty seats alongside. The Lab is
situated in the middle, and the first man is looking quizzically at the
dog when the second man explains that they work for the airline. The airline
rep said, "Don't mind Sniffer; he is a sniffing dog, the best there is;
I'll show you once we get airborne when I put him to work."
 
 The plane takes off and levels out when the handler says to the first
 man,"Watch this." He tells the dog, "Sniffer, search." Sniffer jumps
down, walks along the aisle, and sits next to a woman for a few seconds. It
then returns to its seat and puts one paw on the handler's arm. He says "Good
boy."
 
The airline rep turns to the first man and says, "That woman is in
possession of marijuana, so I'm making a note of this and her seat number
for the police who will apprehend her on arrival."
 
"Fantastic!" replies the first man.
 
Once again the handler sends Sniffer to search the aisles. The Lab sniffs
about, sits down beside a man for a few seconds, returns to its seat, and
places two paws on the handler's arm.
 
The airline rep says, "That man is carrying cocaine, so again I'm making
a note of this and the seat number."
 
 "I like it!" says the first man.
 
 A third time the rep sends Sniffer to search the aisles. Sniffer goes up
 and down the plane and after a while sits down next to someone. He then
 comes racing back, jumps up onto his seat, and poops all over the place.
 
 The first man is really grossed out by this behavior from a supposedly
 well-trained sniffing dog and asks, "What's going on?"
 
 
 The handler nervously replies, "He just found a bomb!"
