What to Expect When Bart's Expecting (S25, E19-549)

This was a 'gag' at the end of the episode.  My reaction: what

Plot Summary
Bartenders across Springfield increase their dwindling revenue for a night by hosting a superhero costume affair which basically boils down to more drinking for much more money.  The shenanigans leave Homer in a particularly hungover state the following morning.

Bart, meanwhile, is forced to go to art class and has particular disdain for the joyful and positive art teacher, Mrs. Trunch.  He gets an idea from Shauna (who is revealed to be Superintendent Chalmer's daughter, whatever) to use voodoo to get rid of Trunch.  Bart follows this advice and after visiting a witch doctor or some sort, he teams up with Milhouse to place a voodoo hex on Trunch, in an attempt to give her a "tummy ache".  The next day, Bart smugly reveals his ploy to the class, but is stunned not only when Trunch comes to class, but also reveals that she does have a specific "tummy ache", but because she's pregnant.  Word quickly spreads that Bart was the one to cause the pregnancy.

Punished, I guess, for what he did, Bart is soon met by a couple having trouble conceiving.  Having heard of what Bart "did" and hoping for a miracle, they ask Bart to use his voodoo on them.  Bart eventually does so, and a few weeks later, the lady of the couple is pregnant and they attribute that fact to Bart.  Soon, Bart starts up a business of using voodoo to hex couples into getting pregnant, until Homer realizes the ploy and confronts Bart over it.  The two don't have long to get into an argument over it, as the two are soon captured by Fat Tony's gang.

Fat Tony demands Bart use his "ability" to breed his horse with a thoroughbred, threatening to kill him and Homer if they fail to get the horses to conceive by morning.  As Bart shares his frustrations over how Homer's poor parenting somehow led to this specific situation, Homer realizes two things: the thoroughbred is gay, and that there's a second male steed in the shack.  The second male, a former Duff Clydesdale whom Homer kinda idolized as a kid, is used by Homer to breed with the female through a musical number, and by morning a pony is on the way, saving Homer and Bart.  The Simpsons visit the horse family a year later to see how they're doing, I guess.

Quick Review
This was a pretty weak episode.  Not a lot of it was funny.  The beginning sequence seemed like an excuse for the writers to let out their inner comic-book geek again (BOY THAT WATCHMEN REFERENCE SURE WAS FUNNY, AGAIN), and aside from a few decent jokes here and there the rest of the episode was a bit of a chore to watch.  Even the use of Fat Tony and his gang, usually a strong source of humor for me, wasn't utilized very well, and the musical number wasn't that funny either.  Really, the score its getting is better than what it should be getting, but that's mainly because nothing about the episode was particularly awful.

Final Score: 6.5
