Springfield Elementary signs a deal with a snack company to install vending machines in the schoolsówith Bart taking advantage of the situation to the point that he becomes obese and suffers a heart attack.
Bart: I've learned that even made-up corporate mascots can lie to you.
Homer: (holding up stuffed animal) Did you hear that Foxie, the Fox Network fox?
Bunny-Ears Lawyer: Tab Spangler is extremely mentally unstable, but is an effective weight loss coach anyway.
Call Back: Homer tries to weasel out of fat camp by suggesting other family members, including "My seldom-seen half-brother Herb [Powell]", who was last seen in season 3's "Brother, Can You Spare Two Dimes?".
Drill Sergeant Nasty: Tab. One fat camp exercise is making the patients pull him on a chariot while he whips them.
Bart: This can't be legal!
Tab: It's legal enough! (cracks whip)
Frivolous Lawsuit: Tab Spangler tells Bart about a family that started a laundry to be able to afford his services and filed a lawsuit claiming the chemicals killed their dog. Tab doesn't believe the claim since it's unusual to see a dog living past the age of 14.
Gratuitous German: Zig-Zagged. One German backpacker calls Bart a "strudel-sucking globenheimer", which isn't a real German word. Later, Homer sings "99 Lüftballons" by Nena in the original German lyrics.
