What is your fave episode?

I don't remember your episode, it's from which season? I have many favorites episodes, i don't know which to choose, here some episodes: - When Homer Simpsons was egoïst throught his family at Christmas and he decided to be generous with everybody, he started to helping people and giving things to others like when he gives his steack at Marge xD. Flanders was a little jealous and gave Christmas's gifts to everyone, then Homer stole all gifts to brun them and thinking that people will be more happy if there aren't gifts because Lisa said that gifts is material things... (don't remember the season) - An horror show, the first episode of this horror show was inspired by "Remember last summer" (i don't know if it's the good translation in English, in French it's "Souviens-toi l'été dernier"). It was when Marge accidentaly kill Flanders with his car. - This episode is from the season 21 (the last), i think it was inspired by a movie but i don't remember which, the story is when Maggy was the children who will give the peace in the world. I love this episode!
