Oakley and Weinstein often stretched characterizations just for one episode to prove the episode's point. It's not done with any subtly especially compared with some foils done in early season episodes (particularly seasons 2-4). I still find though that Lisa's struggle is at least realistic for her character and it is done so well. It's the last great Lisa episode and the last A grade episode I give out. Other than the stretched characters the Simpson gene is the only other fault of the episode. It's a pretty simplistic plot device and makes the resolution almost cringe worthy. Stuff with Herb is so little and obviously continuity doesn't really mean anything in the Simpsons world (and it really shouldn't)
