When the coast is clear, Homer and Marge have inspired sexual intercourse in the hay loft.

Homer and Marge think their marriage has been recharged and go for a romantic weekend at a Bed and Breakfast, but soon fall into their old patterns. However, a maid walks in on them and they conclude they are both aroused when they risk being caught during intimate moments, so they have sex behind window curtains in a room full of people. Their love life is recharged and one day they begin to have sex on the same miniature golf course windmill where Bart was conceived.
