In Killarney, an American tourist sees a sign in front of a farmhouse: "Talking Dog for Sale." He rings the bell and the farmer tells him the dog is around the back. The tourist goes behind the house and sees a black mutt just sitting there "You talk?" he asks. "Indeed." the dog replies. "So, what's your story?" The mutt looks up and says, "Well, I discovered my gift of talking when I was very young and I wanted to be of help to humanity, so I told Interpol about my gift; in no time they had me flying from country to country, sitting in rooms with world leaders, because no one would believe a dog would be listening. I was one of their most valuable spies for eight years running. The jetting around really tired me out, and I knew I wasn't getting any younger. So I signed up for a job at the airport to do some undercover security work, mostly wandering near suspicious characters and eavesdropping. I uncovered some very shady dealings there and was awarded a ton of medals. Then I settled down, had a wife, a dozen or so puppies, and now I'm just retired." The tourist is amazed. He goes back and asks the farmer what he wants for the dog. The farmer says, "Ten euros, sir." The tourist sputters, "But that dog is incredible. Why on earth are you selling him so cheap?" The farmer shrugs and says "Ah well, sir, you, see, isn't he just the biggest liar this side of Croagh Patrick? He's done none of what he told ye."
