A friend told me this absolutley true story from working in her parish rectory last week.
A man came in to see one of the priests and he brought his baby parrot with him. He parrot was just learning to talk. The man asked the priest to baptize the parrot. The priest explained that he could not baptize the parrot, but would bless the parrot. The man insisted on Baptism. The priest told him, "Unless that parrot can say the Act of Faith, I am not baptizing him!"
My friend told me: "I would teach the parrot the Act of Faith, just to see Father's reaction. That parrot can talk, you know, and it's just a matter of time before he brings the thing back to be baptized!"
