A farmer named Muldoon lived alone in the countryside with a wee dog that he loved and doted on. After many long years of faithful companionship, the dog finally died, so Muldoon went to the parish priest:
"Father, my dear old dog is dead. Could you be saying a Mass for him?"
Father Patrick replied, "I am so very sorry to hear about your dog's death. But, unfortunately, I can't say Mass for the poor creature..."
Muldoon said, "I understand, Father, I do. I guess I'll go to this new denomination down the road; no tellin' what they believe... Do you think $500 is enough to donate for the service?"
Father Patrick: "Why didn't you tell me your wee dog was Catholic?!"
