Sniff Sniff...

A man had just settled into his seat next to the window on
the plane when another man sits down in the aisle seat and
puts his black Labrador in the middle seat next to the
man...The first man looks very quizzically at the dog and
asks why the dog is allowed on the plane.The second man
explains that he is a Drug Enforcement Agency officer and
the dog is a 'Sniffer dog'. 'His name is Smithy
and he's the best there is. I'll show you once we
get airborne, when I put him to work.' The plane takes
off, and once it has levelled out, the agent says: Watch
this.' He tells Smithy to 'search'.Smithy jumps
down, walks along the aisle, and finally sits very
purposefully next to a woman for several seconds. Smithy
then returns to his seat and puts one paw on the agent's
arm.The agent says, 'Good boy', and he turns to the
man and says: 'That woman is in possession of marijuana,
so I'm making a note of her seat number and the
authorities will apprehend her when we land.' 'Say,
that's pretty neat,' replies the first man. Once
again, the agent sends Smithy to search the aisles. The Lab
sniffs about, sits down beside a man for a few seconds,
returns to his seat and this time, he places TWO paws on the
agent's arm. The agent says, 'That man is carrying
cocaine, so again, I'm making note of his seat number
for the police.' 'I like it!' says his seat
mate. The agent then tells Smithy to 'search' again.
Smithy walks up and down the aisles for a little while, sits
down for a moment and then comes racing back to the agent,
jumps into the middle seat and proceeds to shit all over the
place. The first man is really amazed now by this behaviour
and can't figure out how or why a well-trained dog would
behave like this, so he asks the agent 'What's going
on?' The agent nervously replies, 'He just found a
bomb.'
