A man is driving along a highway when he sees a sign that says, "Talking dog for sale." Intrigued, he pulls over and walks up to the owner of the dog.
"How much for the talking dog?" he asks.
The owner replies, "Well, he's a pretty special dog, so I'll need $500 for him."
The man is a bit skeptical but decides to take a chance and buys the dog. As he's driving away, he can't resist asking the dog a question.
"So, can you really talk?" he asks.
The dog looks up at him and says, "Of course I can talk. Why do you think I let you buy me for $500?"
The man is shocked and asks the dog how he learned to talk.
The dog replies, "Well, I used to work for the government as a spy dog. I was trained to listen in on conversations and report back to my handlers. But I got tired of all the sneaking around and decided to retire and live a more laid-back life."
The man is amazed and asks the dog if he has any other special abilities.
The dog grins and says, "Oh, I've got plenty of tricks up my sleeve. For example, I can play the piano, do backflips, and even juggle with my tail!"
The man is blown away by the dog's talents and starts thinking about all the amazing things they could do together. But just as he's getting excited, the dog interrupts him with a sly grin.
"Hey buddy, wanna hear a joke?"
The man chuckles and nods, eager to hear what the talking dog has to say.
The dog clears his throat and says, "Why did the bicycle fall over? Because it was two-tired!"
The man bursts out laughing, realizing that he's just bought himself the best friend and comedian he could ever ask for. And from that day on, they traveled the country together, spreading laughter wherever they went.
