Little Johnny...
A priest was walking along the corridor of the parochial school near the
preschool wing. A group of little ones were trotting by on the way to the
cafeteria. Little Johnny stopped, looked at his clerical clothes and asked,
"Why do you dress so funny?"
He told Johnny he was a priest and this is the uniform priests wear.
Little Johnny pointed to the priest's plastic collar tab and asked, "Do you
have an owie?"
The priest was perplexed till he realized that to him the collar tab looked
like a band-aid. So the priest took it off and handed it to Little Johnny,
to show him. On the back of the tab were raised letters giving the name of
the manufacturer.
Little Johnny felt the letters, and the priest asked, "Do you know what
those words say?"
"Yes I do," said Little Johnny, who was not old enough to read. Peering
intently at the letters he said, "Kills ticks and fleas up to six months!"
