A guy sees a sign in front of a house: “Talking Dog for Sale – $10.”
Curious, he walks in and asks the owner, “What’s the deal?”
The owner points to the backyard.
The man walks up to the dog and says, “Can you really talk?”
The dog replies, “Yep. I used to work with the CIA. I’d sit in rooms and eavesdrop on world leaders, passing valuable intel. I’ve even won medals for it.”
Amazed, the guy asks the owner, “Why on earth are you selling this dog for $10?”
The owner replies, “Because he’s a liar! He didn’t do any of that!”
