A guy was walking down the street when he noticed a sign in a yard that said "Talking Dog For Sale". Curious, he saw the owner sitting on the front porch and went up to ask him about the dog--"Hey have you really got a talking dog"?--The guy says "Yeah, he's a black lab in the back yard--you can go see him if you want"--The guy goes back and here's this lab sitting in the yard--He feels stupid but says to the dog--"Hey, can you talk?"--The dog looks up at him and says "Sure I can Talk!" Flabbergasted, the guy says "Wow, so what's your story?" The dog proceeds to tell him his lifetime history--"I was just a pup when I learned I could do human talk and spent a long time deciding what I was going to do with this gift--I decided to offer my services to the CIA--Who would think that a dog would be a spy, and I got to go all over the world as a pet listening in on conversations among the world's leaders and gathering secrets for my country--After years of intelligence-gathering I got tired of world travel and decided to settle down--I got married and had some pups and here I am, just living out the rest of my days"--The guy couldn't believe it, but thanked the dog and went back out front to the owner--"How much do you want for the dog?" he asked. The owner replied, "Oh I don't know, how about ten bucks?" The prospective buyer says-"You've got to be kidding me--ONLY TEN BUCKS for a talking dog?

The owner casually responds--"The dog is a chronic liar--Did he tell you his CIA story? Total fabrication--He's never left the house!"
