A beefed up version of my R*R review
A season 9 highlight and Oakley and Weinstein's last hurrah. There claim that it is the best written episode of the series does seem like a bit of a stretch though.
Amusing if throwaway Frostillicus b-story gives us quite a few laughs, including the Offensive Ballcap(show me your t- Hey!), Apu's Freak-E-Mart (later Nude-E-Mart) , some good Jasper lines(see below), and Apu's novelty pens (Oh no! Her clothes are coming off!).
For me, the Simpson Gene works as a one-off episode idea like HOMR, amd MagicalManFromHappyLand's explanation of Lisa's intelligence drop actually being a confidence drop seems plausible.
There are many great visual sequences including Bart and Homer watching TV, the pan across Lisa's mirror, Homer dancing to Lisa's off-key sax playing, Troy McClure's genetics film, When buildings collapse, Bart's homework grades and Homer talking to his male relatives.
On rewatch, I noticed that they used a lot of Ralph, including Lisa's future fantasy, instead of Milhouse.
Ms. Hoover: Very nice, Janie. Good use of pipe cleaners, Becky. DON'T open it Ralph!
I'll just give you a C-.
Grampa: Oh no, no. No! The George Raft look is dead! I wanted Audie Murphy.
Grampa: Maybe you're just a lousy cook. Ow!
Marge: I'll go get the Bactine.
Apu: Behold, the Can of Mystery! The label vanished many years ago. What strange wonders lie inside? Treasure? Dog food?
Lisa: Oh Kenny, Look at the interplay between light and shadow. It's so luminous and vibrant.
Kenny: Oh, thanks Lisa. I painted that one. The real one's in my garage.
(I don't think this joke gets noticed very much, but I love it)
Man: Sounds like she's hitting a baby with a cat.
Lisa: You have to listen to the notes she's not playing.
Man: I can do that at home.
Jasper: By gum, it worked. I've awakened in the future. Moon Pie. What a time to be alive.
Apu: Return to your state of living death at once, Sir!
Jasper: Is that you Apu? Whoa! Time has ravaged your once youthful looks.
Lisa: I am! I'm strongly opposed to Proposition 305.
Station Manager: You're against discount bus fares for War Widows?
Lisa: Uh, you bet I am.
Station Manager: OK. Make-up!
Lisa: I'm supposed to talk to you about Proposition 305..
Homer: Mooching War Widows.
Homer: Marge, get me your address book, 4 beers, and my Conversation Hat.
