A priest went to buy a parrot."Are you sure it doesn't swear?" asked the priest."Oh absolutely. It's a religious parrot," the storekeeper assured him. "Do you see those strings on his legs? When you pull the right one, he recites the lord's prayer, and when you pull on the left, he recites the 23rd Psalm.""Wonderful!" said the priest, "but what happens if you pull both strings?""I'll fall off my friggin' perch, you idiot!" screeched the parrot.
