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.
Bill may also get this, at least after watching him in "Chokin' and Tokin'" and "Smooching and Mooching".
Foe Yay: Kowchevski with Daniel, (whom he dislikes intensely) as seen in this quote:
Kowchevski: Lindsay, Daniel's cute and all with his stringy hair and bedroom eyes, but he's a loser.
Fridge Brilliance: Consider that very last scene again: Lindsay (and, sadly, the show itself) are on the way to the land of the Dead.
"Funny Aneurysm" Moment: In 2014, James Franco was caught flirting with a 17-year-old girl, which makes his occasional flirting with Lindsey a little squicky.
Hilarious in Hindsight: Daniel is viewed by pretty much everyone in the show as a burnout and no-hoper with no shot at (or interest in) higher education. In real life, James Franco has four degrees, was pursuing two more as of 2011, and has taught classes at NYU and USC.
Neil's brother Barry (played by David Krumholtz) comes to visit for the weekend from college. There is an entire scene dedicated to his frustration that people expect him to have a major picked out and he says earnestly that he's "Undeclared".
Judd Apatow stated in the commentary for "The Little Things" that he deliberately had Ken accidentally bang his head against Amy's tuba during their make-up session to prevent the scene from becoming this.
Gilmore Girls fans will recognize several people: Dean's Navy friend Kyle is Alan the bully, Mr. Rosso is the rival troubadour, Logan is a rival high school athlete in one brief scene, and Tanna is one of Lindsay's fellow Matheletes.
Tear Jerker: Lots of moments, especially if the show was anything at all like your growing up experience.
The Halloween episode, with Lindsay (albeit briefly) abandoning a tradition that her mother treasures, and her mother hearing that parents are throwing away her cookies out of concerns for safety. And then there's Lindsay's reaction when she realizes that it's Sam that she egged...
The episodes "Carded and Discarded," "Kim Kelly is My Friend," "The Garage Door," and "Discos and Dragons" can be real floodgate openers.
Bill watching TV alone in "Dead Dogs and Gym Teachers".
Nick's audition in "I'm with the Band." He looked so broken and forlorn afterwards that Lindsay had to kiss the poor guy to cheer him up.
Nick, again and again, although everyone has their episode. Neal in "The Garage Door" and "Noshing and Moshing" and Millie in "Dead Dogs and Gym Teachers".
Sam is another constant Woobie, but it is definitely highlighted in "Tricks and Treats" when Lindsay and Kim egg him without realizing it.
Kim qualifies as a Jerkass Woobie. She can be very cold and nasty to people, even when they're trying to be nice, but her family and home life is so horrible you can't help but want to give the poor girl a hug.
Similarly, Daniel is manipulative and lazy and seems set on doing as little as possible in life. But his father is sick, his mother obviously doesn't think much of him, his teachers seem set on making sure he never succeeds, he's thought of by everyone as a failure by default and even his closest friends can't see him with any type of future. He seems caught in a vicious cycle: Everyone assumes he's a screwup, he tries to prove them wrong but it doesn't work, he becomes indifferent and complacent, and everyone thinks he just doesn't care.
