Homer and Marge spend the night at an inn, called the Aphrodite Inn, to spice up their sex life. The inn was partly based on the Madonna Inn, which, as in the episode, features different kinds of sex-oriented rooms with unusual names that are supposed to spice up a couple's love life. See more »

Grampa and Homer At Their Best
19 March 2018 | by Gerardrobertson61See all my reviews

Love any episode where Grampa and Homer are in it together most of the time, and this is another classic father and son episode. Watching Grampa selling his medicine and the result of it was very funny. This is The Simpsons at their best, and I could watch Grampa and Homer at any time, just love them.
