A passenger on a plane is sitting next to a large man with a dog on his lap, so he asks “is that a guide dog?” The man replies “no, I'm a security guard and he's a sniffer dog...watch this” and he whispers something into the dog's ear. The dog immediately rushes off down the ailse, comes back and puts one paw on the guards knee....the guard says 'heroin' and makes a note in his book of the seat number.
The man says “that's amazing”...the guard says “yep, he's pretty good” and whispers again into the dog's ear. The dog rushes off again, comes back and puts both paws on the guards knee...the guard says “cocaine” and makes another note in his book of the seat number.
The man is totally entralled by this dog and asks the guard to demonstrate the animal's abilities once more, so again the guard whispers into the dog's ear and away he goes. This time he comes back, jumps up onto the guards lap, buries his head and lays there shaking uncontrollably. The man asks “why is he doing that?”
The guard replies “he's found a bomb......”
