No, humor is in the speed bump. Whether or not the idea of a woman's lover being a priest shocks or amuses, the fact that the kid doesn't know that his father has coincidentally chosen the adulterer to urge a confession, which is revealed in the response to 'It's dark in here.' is the source of the humor. BAM! suddenly the lover is a priest, and suddenly the confessor has a reason not to force the boy to confess. Dad's in for disappointment either way.That's supposed to be funny because priests are morally superior, and thus would never sleep with another man's wife.
Which then leads to wondering, 'Where does a priest get 1000 dollars?'
From what I understand, priests generally get more spending/pocket money than others in the church. Monks and nuns can be quite bitter about that.
