A nun goes to the priest and says "father, there's a hole in the roof of your church."

"Thank you for telling me," he replies "but you've been here for years, it's our church."

The next day the nun goes to the priest and says "father, there's a broken window in your- I mean, our, church." He thanks her again and calls for a repairman.

The following day the priest is preparing for a visit from the local bishop. As he is weeding the gardens, he cuts his hand. Calling the nun over he says "there's a bottle of rubbing alcohol in my quarters somewhere, could you fetch it for me?" The nun nods and goes looking for it.

It is as the priest is greeting the bishop that she returns from the church and loudly announces "father, don't worry about the weed, the alcohol was under our bed!"
