While Marge was reading "Love in the Time of Scurvy", she daydreams about dating the sexy pirate from the book, and they're seen on a ship together. Marge says that the seas were certainly heaving, to which the sexy pirate says that the seas are no more than Marge's bountiful bosom. Marge notices the earring on the pirate's right ear, and asks him if the earring means that he's a pirate, and he responds, "Kind of." He then notices the sea getting quiet, so he tells Marge that the seas have quieted, and just before he finishes his sentence about his love for Marge, a saxophone abruptly plays (which turns out to be Lisa playing her sax). The pirate then says that the sax is such noise, and that he's done for the evening.
Marge's Dream Lover recently appeared in The Simpsons: Tapped Out as a limited time character who's part of the Pirate Ship, which is the final prize of Act 3 of the Time Traveling Toaster 2017 event.
