In her esteemed opinion, these particular ones stand head and shoulders above the rest, even though outsiders may consider others to be the top Simpsons episodes. Some of her favorites are from the early seasons, which she claims are the greatest. She made this list on the Ranker Podcast, which you can listen to above.
"This was the episode where he was the exchange student. It was around season five. He gets kidnapped by these guys who make wine.
