Talking Dog For Sale

This guy sees a sign in front of a house: "Talking Dog for Sale."
> He rings the bell and the owner tells him the dog is in the
> backyard. The guy goes into the backyard and sees a black mutt
> just sitting there.
>
> "You talk?" he asks.
>
> "Yep," the mutt replies.
>
> "So, what's your story?"
>
> The mutt looks up and says, "Well, I discovered this gift pretty
> young and I wanted to help the government, so I told the CIA
> about my gift, and in no time 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 eight years running.
>
> "The jetting around really tired me out, and I knew I wasn't
> getting any younger and I wanted to settle down. So I signed up
> for a job at the airport to do some undercover security work,
> mostly wandering near suspicious characters and listening in. I
> uncovered some incredible dealings there and was awarded a batch
> of medals. Had a wife, 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.
>
> The owner says, "Ten dollars."
>
> The guy says, "This dog is amazing. Why on earth are you
> selling him so cheap?"
>
> The owner replies, "He's such a liar. He didn't do any of that stuff." Tweet
