A priest at a parochial school…

A priest at a parochial school, wanting to point out the proper behaviour for church, was trying to elicit from the youngsters rules that their parents might give before taking them to a nice restaurant.
“Don’t play with your food,” one second-grader cited.
“Don’t be loud,” said another, and so on.
“And what rule do your parents give you before you go out to eat?”
the priest inquired of one little boy.
Without batting an eye, the child replied, “Order something cheap.”
