Previous episode reference:
Solar system chart (Bart memorized the solar system chart because he was so disgusted by something he saw in school, and got a good grade; unfortunately, I can't remember which episode this is)
Comments:
Lisa in curlers. Why does Lisa need curlers? She's got POINTY hair; I wouldn't think she needs curlers for that. And we didn't see her in curlers in "Little Big Mom", the last episode where she was being a mother.
Lisa using Maggie as an example for how Bart wanted Greta. I wonder if this has anything to do with how we ATSers complain about Maggie not getting used enough. (I made the same comment regarding the recent couch scene in which OFF appear on a slot machine.)
