A man is driving down the road when he sees a sign saying 'Talking Dog For Sale'
He rings the bell and the owner appears and tells him the dog is in the back garden, so he goes round the back and sees a nice looking Labrador retriever sitting there.
'You talk?' he asks.
'Certainly do,' the Lab replies.
After the guy recovers from the shock of hearing a dog talk, he asks 'So, what's your story?'
The Lab looks up and says, 'Well, I discovered that I could talk when I was pretty young. I wanted to serve my country so I told the SAS. In no time at all they had me jetting from country to country, sitting in rooms with spies and world leaders, because no one figured a dog would be eavesdropping.'
'I was one of their most valuable spies for eight years running but the jetting around really tired me out, and I knew I wasn't getting any younger so I decided to settle down. I signed up for a job at the airport to do some undercover security, wandering near suspicious characters and listening in.
I uncovered some incredible dealings and was awarded a batch of medals. I got married, had a mess of puppies, and now I'm just retired.'
The guy is amazed. He goes back in and asks the owner what he wants for the dog.
'Ten quid,' he says.
'Ten quid? But this dog is amazing! Why on earth are you selling him so cheap?'
'Because he's a liar. He's never been out of the garden'
