(Since this is a christian movie, it tackles a lot of different issues on sin)
A woman wears tight fitting outfits throughout the film.
In one of the skits where "satan" a character on a TV show sings, 2 women wear short outfits.
In a dream sequence the main character (who is amish) see's the girl he loves getting dressed (behind a tree with no view of her) in amish clothing. This is very funny and no nudity is shown.
Roy (when he was drunk the night before) left his wallet at Tiffany's house. She brings it to him and says "You left this at my place big boy." Everyone thinks that he slept with her, we later find out that he passed out by the time they arrived at her house and that nothing happened.
Tiffany is released from prison for "good behaviour" and one man says "I think it had something to do with the warden's bachelor party." Showing that Tiffany is a temptress.
