Sniffer

A man had just boarded and settled into his seat next to the window
on the plane when another man sat down in the aisle seat and put
his Black Labrador in the middle seat next to the man.

The first man looked very quizzically at the dog and asked 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.
I'll show you once we get airborne, when I put him to work.'

The plane took off, and once it has leveled out, the Policeman said,
'Watch   this.'

He told Sniffer to 'Search'.

Sniffer 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', and he 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.

'Gee, that's pretty good,' replied the first man.

Once again, the Policeman sent Sniffer to search the aisles.

The Lab sniffed about, 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, '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 his seat mate.

The Policeman then told Sniffer to 'Search' again.

Sniffer 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 shit all over the place.

The first man was really disgusted by this behaviour 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.'
