These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Music of Awesome: "You Can't Always Get What You Want" for the season 2 finale. Perfect for both the Tear Jerker of Lucy winning custody of Hope over the Chances and the Awesome Moment of Lucy getting hit by a bus.
Also both instances of "Danny's Song."
Ear Worm: Watch episode three. Get "Istanbul" stuck in your head for the following week.
Fridge Brilliance: Why does Maw Maw know all the skills she does, notable mechanical skills? Given her age, she'd likely have been Rosie The Riveter worked in a factory during World War II building military machines.
In season 1 ("Snip Snip"), Burt tells Jimmy that the day Jimmy was born was the best day of his life, despite the pregnancy being unplanned. A later episode reveals that Burt actually invokedThe Baby Trap on Virginia, so it would make sense that he wasn't too unhappy about it.
Fridge Horror: Before she's even old enough to talk, Hope has watched her mother die twice. And she was a serial killer. And despite being a serial killer, she still loved her daughter. It may be quite a depressing thought once Hope is old enough to put the pieces together there.
"Funny Aneurysm" Moment: Burt and Virginia tried to get Maw Maw into a nursing home, but none of them would take her. One episode has her get sent to one when she is taken away by Social Services.
Hilarious in Hindsight: In a episode of Garcia's last series, it had Earl trying to made amends to his former teenage babysitter and her boyfriend who got pregnant when Earl poked holes in the guys condom. When he visits them, he finds out they got married pretty young and actually have a happy marriage, even with a slacker son who lives with them. This pretty much describe the grandparent Chancesnote Including poking holes to the condom.
There was also the episode of Earl helping Randy find a girl he had a summer romance with when he was a kid. Its then turns out it was Joy. Those two would then quest-star as a married couple.
This happens a few times. With Burt making elaborate tricks to manipulate Jimmy into hugging him, just to "feel your chest against mine". In one episode after Burt kissed Jimmy on the lips, Jimmy asks him not to try that again. Burt responds whispering "Stop making me want to." Later in the episode, Burt (while high on meds) got excited while Jimmy was shaving his genitals because he forgot who it was for a moment.
Moe: Shelley (she is, after all, played by Kate Micucci).
Paranoia Fuel: Both in-universe and out, the idea of spiders entering your ear and laying eggs while you sleep.
Shipping Bed Death: Humorously referenced by Burt and Virginia when Jimmy and Sabrina get together, wondering if their relationship will be as interesting now that the UST is resolved. Burt jokes that there is a girl at the copy place with a boyfriend, so he can transfer that same pattern somewhere else. To the shows credit, Jimmy/Sabrina was never a mainstay of the shows plots and that same episode went out of its way to demonstrate that there is still plenty of story to tell between the two.
Squick: The beginning of the second episode has a scene where Jimmy walks in on Maw Maw attempting to breastfeed Hope. To say nothing of her french-kissing her great grandson in the pilot, believing him to be her long-dead husband.
This is pretty much Maw Maw's entire shtick. Another "great" example is the episode where she thinks she's in labor (and Jimmy's dad ends up helping deliver... something.)
Burt giving his son Jimmy a several second-long kiss on the lips, then requesting he take offhis pants.
Tear Jerker: In Don't Vote for this Episode Burt and Virginia realized Maw-Maw was getting dementia when she chastised them for being late for her birthday dinner (which was days before) and was angry that Virginia's grandfather didn't call to tell her he was going to be late. Maw-Maw's reaction when Virginia told her he was dead is just so heartbreaking.
The look on Jimmy's face when he's forced to hand Hope over to Lucy, after losing the trial is absolutely heartbreaking.
The flashbacks/flashforward in "Arbor Daze", watching both a young Sabrina and an older Hope get neglected by their parents. With Sabrina's treating her as a nuisance at best and Hope's working two jobs each just to afford her Christmas presents. Then we see each talking to a doll about how things would be different with their own children, how they'd be there for them and be better parents than their own.
