A small town church is trying to increase its attendance, and decides to hold a contest encouraging all their parishioners to invite guests to come to service. The parishioner who gets the most new people to attend that Sunday will win a prize.
A small family happens to be traveling through the area, and they see the church and decide to slip in and watch the service. Quietly, they crack the chapel door and try to discreetly take seats in the back. The priest notices the newcomers, assumes they are attending as part of the contest, and calls out in front of the congregation "Well now, who invited you?"
