Question: Near the beginning of this episode, there is a heating repairman. He asks "Does anyone want to hear the story of the love I once had and lost?" or something like that. Is this character supposed to be the professor from Marge's flashback? He is also seen later on sitting with the kids and listening to Marge's narration, but then he just disappears from the story with no explanation. The purpose of introducing and then abandoning this character is lost on me.
