Mostly just silliness, the idea that humble elementary school principle Skinner is in actual competition withDr. Lubos Kahoutek, who is not a school principal, but a published professor makes the humor of the scene. The “little boy” implies that Kahoutek had a kid working with him much like Bart was. After that its an Oz reference, Little Boy = Little dog.
It think its a rip of an old Johnny Carson routine where he’d do a character with that voice who taste something and say “Mmmmmm that’s good <something>” the something was often a double entendre or drug reference.
Or it could be from an old SNL commercial for the “Bass-0-matic”, the commercial was done primarily by Dan Ackroyd, but one cut away to one of the female cast drinking the liquified fish and saying “Mmmmmm that’s good Bass!”
Cadets at the military school:
“It was worth sneaking into town. That was some gooooooooood corn!”
I also thought, perhaps incorrectly, that this was also vaguely referencing the movie “Chuck and Buck,” where one of the characters mentions playing Chuck and Buck’s Fuck and Suck.
I have 2 jokes I don’t understand:
1: Lisa The Veterinarian: The Simpsons go to the water park. Bart asks Milhouse how long he’s been waiting in line and he responds, “you didn’t use the app last week to get your Slammin’ Salmon line number? What are you, Amish?” I don’t really understand that joke.
2: Home Sweet Homediddly-Dum-Doodily:
Bart gets lice from playing with Milhouse’s monkey. Bart says “how come I get lice and nothing happens to Milhouse?” We then see Milhouse is pale and shaking saying " so cold, so very very cold" I don’t understand why Milhouse would be shivering
Regarding #2, Milhouse appears to have gotten some sort of tropical illness from the monkey.
And regarding #1, it’s probably a slam on anyone who doesn’t have the latest app for…whatever. Like in the Weird Al song “First World Problems” one of the lines is: My Sonicare won’t charge/Now I have to brush my teeth like a Neanderthal!
It’s a variation of a rarely used trope.
Example: [Extremely tense scene] Man dramatically pulls out document. “Eggs, milk…” “Damn it, this is my grocery list.”
You can get FastPasses for the large rides at Disney parks up to 30 or more days ahead of time online which allow you to pass the queue if you go at your designated time.
That’s a reference to Mel Blanc’s character from the radio (and later TV) show: The Jack Benny Show. A running gag was that wherever Benny went, he was bound to turn around somewhere and there Mel would be (as a waiter, bellboy, policeman, anything) and say “Yeeeeesssss!!!?” To which Benny replied, “Oh, not you again.” Cue the guaranteed laughs.
As was mentioned 17 years ago 
, the actor being parodied was not Mel Blanc, but Frank Nelson.
Well it’s been 17 years, but since it’s been bumped, several posters seem to be under the impression that the previous establishment was actually called “Chuck’s Suck and Fuck”.
The clear joke is that it was obviously just called “Chuck’s Seed and Feed”, and any connections you make to another title is your own dirty mind.
Yeah. As if a brothel could be easily converted into a livestock food store.
You have obviously never been to Northern Nevada.
