A guy is driving through Tennessee country side and he sees a sign that reads TALKING DOG FOR SALE. He drives up the lane and ask the farmer sitting on the porch "Do you really have a talking dog for sale". "He's tied up in the barn" says the farmer. So the guy heads for the barn, sees the dog and ask "Can you really talk?" "Yep" says the dog. "What's your name?"...."Rover" says the dog...."This is wild, I never heard of a talking dog" .... so the dog tells him "they found out I can talk when I was just a pup and as soon as the government found out I was immediately recruited into the CIA (Central Intelligence Agency) and I spent the next 8 years jetting from country to country, sitting in on secret meetings with Heads of States and their spies and such and of course they didn't suspect a thing having a dog in the room so I was the best secret agent the governemnt. But after 8 years the travel got the best of me, that's what, 57 human years? So I decided to come back here and work at the airport hanging around suspicious looking travelers and such and I was awarded all sorts of accomodation medals for the work I did at the airport. Eventually that pretty little thing over there dropped a litter of 9 puppies so I decided to stay here and help her raise them and here I am". "That is an incredible story" says the traveler so he goes to the farmer and ask how much he wants for the dog. "Ten dollars" says the farmer. "Ten dollars for an incredible dog like that? Why are you selling him so cheap"? The farmer says "because he's a liar, he didn't do any of that stuff".
