"You talk?" he asks. "Yep," the dog replies.
After the guy recovers from the shock of hearing a dog talk, he says "So, what's your story?"
The dog looks up and says, "Well, I discovered that I could talk when I was pretty young. I signed up for a job at the airport to do some undercover security, wandering near suspicious characters and listening in. I uncovered some incredible dealings and was awarded several medals. I wanted to help America, so I interviewed with the the CIA. In no time at all they had me traveling around the world and hanging out with spies and world leaders. After all, no one figured a dog could eavesdrop. I proved to be one of their most valuable spies for a decade. But the jetting around really tired me out, and I knew I wasn't getting any younger. So, I decided to settle down. I got married and had a mess of puppies. Now I'm just retired."
"Ten bucks," the guy says.
"This dog is amazing! Why on earth are you selling him for just ten dollars?"
"Because he's a liar! He never did any of that stuff!"
He was identifying shapes when he decided to talk to God. "God," he said, "how long is a million years?"
God answered, "In my frame of reference, it's about a minute."
The man asked, "God, how much is a million dollars?"
God answered, "To me, it's a penny."
The man then asked, "God, can I have a penny?"
God answered, "Sure! Just a minute."
