A lady (returning from holiday in Spain) is sitting in the aircraft (awaiting departure), when a man walks into the cabin along with a Cocker Spaniel dog and sits down next to her.
Lady: Excuse me but I thought animals were not allowed to travel with passengers in the cabin?
Man: That's correct, but this dog is classed as ground crew and allowed to travel with it's handler.
Lady: So what does it do then?
Man: It's a sniffer dog, trained to search and locate contraband, etc.
Lady: Really - any chance of a demonstration then?
Man: Yeah ok - can't so any harm.
The dog is released and promptly runs off for a search. Five minutes later it returns, sits down and places a paw on the man's leg.
Lady: What does that mean then?
Man: Looks like he's found someone with a load of tobacco, but that's not a problem.
Lady: Can he do that again then?
The dog is released again and promptly runs off for a search. Ten minutes later it returns, sits down and places two paws on the man's leg.
Lady: What does that mean then?
Man: Looks like he's found someone with a load of drugs, we'll deal with that at the end of the flight.
Lady: I'm impressed - one more?
Man: Okay last time.
Again the dog is released and (as before) promptly runs off for a search. Twenty minutes later it returns, pooes in the isle and starts shaking.
Lady: Good heavens is that supposed to happen, or does it mean something?
Man: Very serious I'm afraid - looks like he's found a bomb.
