Mighty Roar: The bus driver from Shelbyville is scared off by this.
Nervous Wreck: Marge when the stress of errands gets to her — while driving.
Parental Neglect: Homer when he's looking after Maggie, but in his defense he did try to care for her and no one saw her running off to find Marge and as soon as he knew, he looked all over for her and called the police.
Police Are Useless: Through he has grounds to have her in jail, Wiggum had to let Marge go and he doesn’t notice the mobster with a body in car who’s held up.
What Do You Mean, It's Not for Kids?: In-Universe; one of the "hottest R-rated movies Europe has to offer" at Rancho Relaxo is The Happy Little Elves Meet Fuzzy Snuggleduck. For those who don't remember the early days of The Simpsonsnote ("early" as in "back when it was a sketch on The Tracy Ullman Show and back during the first season when the animation was cruddy, the episodes focused on Bart and Lisa, and the pacing was slow), The Happy Little Elves was an overly-cutesy kids' show (kind of like The Smurfs) that Lisa and Maggie loved (but Bart hated, because he was into The Itchy and Scratchy Show). The joke here is either a Take That to people who think cartoons are for kids (which was also something The Simpsons itself had to struggle with during its early years) or a reference to how most foreign movies and TV shows (particularly in Europe) are more lenient with risqué content than America is.
