After officiating at a baptism the priest was invited back to the parents home for tea and cake. He changed out of his vestments and went to the home where one little 4-year old boy kept staring at his white collar.

The priest finally said to the little boy, "Do you know what the white collar means that I am wearing?"

"Yes I do.", the little boy said.

"It means that you won't have flees or ticks for three months."
