History
When Homer and Marge were in their makeshift shack at The Cabins at Honeymoon Mountain, Homer told Marge that they were lucky to have a warm shelter, water, and love. Marge thought that what he said was sweet. Homer then told Marge that he meant the massage oil and squirted some Love Oil onto the fire.
