Joke.

Man sees a sign in front of a house: "Talking dog on sale".

Stops by.

Says to homeowner: "You have a talking dog on sale?"

Homeowner: "Yeah, he is in the back".

Man: Goes back. Sees the dog sitting next to his small house. He feels silly saying it but he does: "Are you the talking dog?"

Dog: "Yeah. I am retired. I used to be a military dog helping find landmines, survivors etc. Then I joined the police, sniffing out all kinds of stuff and helping keep the world safe from criminals. Then I was cast in couple of movies @ Hollywood.

Now I am just raising my puppies".

Man was impressed. Goes back to the house and asks the homeowner: "How much for the talking dog?"

Homeowner: "Ten bucks."

Man: "Why so cheap?"

Homeowner: "He is a damn liar. He didn't do nothing".
