A guy saw a sign in front of a house that read, “Talking Dog for Sale.”

He rang the bell, and the owner said the dog was in the backyard.

The guy went back and saw a black mutt sitting there.

“You talk?” he asked.

“Yep,” the dog replied.

“So what’s your story?”

The dog looked up and said, “Well, I discovered my gift at a young age and wanted to help the government. I told the CIA, and soon I was flying all over the world, sitting in rooms with spies and world leaders. No one ever suspected a dog.”

“I was one of their top spies for eight years. After that, I got tired of traveling, so I worked undercover at the airport, listening in on suspicious people. I uncovered incredible plots and was awarded a bunch of medals.”

“I had a wife, lots of puppies, and now I’m retired.”

The guy was amazed.

He went back inside and asked the owner how much he wanted for the dog.

“Ten dollars,” said the owner.

“Ten dollars?!” the guy said. “This dog is incredible! Why are you selling him so cheap?”

The owner replied, “Because he’s a liar. He didn’t do any of that stuff.”
