Oldie, probably a repeat, but goody
Young bachelor goes to his local parish where he went to school, had his first communion and attended Mass regularly. He tells the priest that his long time companion, a beagle, had died and asked the priest if he could have some sort of church funeral service for him. The priest told him definitely not, we only hold services for members of the church. He then suggested he go down the street to any of those Protestant or other denominations, they would more than likely accommodate him. The young man then asked if two thousand dollars would be enough of a donation. Before he could walk away, the priest grabbed him by the arm and said "Hold on a minute son, you didn't tell me the dog was Catholic".
