1 point for the episode/main plot.
1 point for the joke/scene.
Old grey points just ain't what she used to be, ain't what she used to be, ain't what she used to be.
Hmmm, I'll try, but most probably I'll be wrong. Also, I have watched the Latin American dub so I may be wrong about some words:
There is one episode where there is a new girl at the school, and near the end she organizes a dance. Same episode when Homer started selling fat/lard/whatever. Near the end Marge tries to convince Lisa to attend the dance, and says something along the lines of "we can organize a dance here at home" and Lisa is like "nope, I'll go to the dance at school".
