Well, I've said it before, but endings, endings, endings! The first act, with Bart's prank in particular, got my hopes up for a really fun episode, and I was enjoying Lisa's "Sound of Music" story with Cletus's kids as well... but it really went downhill somehow in the last act; I suppose the extra bit with Bart's psychologist wasn't too bad, but once Lisa had to get the kids out of Krusty's tour, eh, blah. To add more of a sour note to the ending, I have to wonder why the (admittedly somewhat token and bound to get cut off by Fox) song medley usually found in the credits of these episodes did not appear this time. But like I said, otherwise I found it pretty enjoyable.
DYN: ...Bart uses the correct past tense of "hang" (meaning to execute by hanging)? ...the TV-PG rating appeared at the start of acts 1 and 3, as opposed to its usual spot of the opening and (recently) act 2? ...Witney Spuckler spells her name as such (i.e. without an H)?
Previous episode references 2F15: The vending machine in the couch gag is like the soy pop machine (more so, anyhow, than any food-vending machine I've ever used) AABF15: Outsider art (this time with the cat lady) used FABF17: "The Sound of Music" plot elements also used
Goof Lisa says "cognoscentis," even though cognoscenti is already plural. (The singular form is -scente, so perhaps it was really "cognoscentes"?)
Meta-reference corner -GARY Chalmers? Well, OK... -Also, of course, Bart's nightmare of being in a family of cartoon characters, whose success also led to the Fox News Channel, and -Bart's psychoanalysis of "don't have a cow"
Other stuff The way Lisa falls down a rocky cliff during her "The Hills Are Alive" definitely reminded me of a similar gag in the opening to several episodes of Al Jean and Mike Reiss's "The Critic."
Also, I am guessing that the Dark Stanley sequence was meant to be a reference to something. The accordion music made me think first of "Amelie" (not that I thought it was a reference to *that*), and I know its director Jean-Pierre Jeunet also made a movie called "Delicatessen" which involves cannibalism - and which I haven't seen. Is that it?
