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.
YMMV: Homestar Runner
Accidental Innuendo: In "coloring", Strong Bad attempts to color in a page of the Limozeen coloring book with one of the "crayons" he got from Marzipan called "Dermal Discoveries" (a nod to the real life renaming of the "Flesh" crayon to "Peach"). He then tells the band to "prepare themselves for a dermal discovery". Considering this is addressing a band, it could be intentional.
Big Name Fan: Due to the site's popularity, there are several. In fact, there are so many that the fan wiki has to use multiple pages to list all the references to the site in pop culture.
Dude, Not Funny!: Some of Strong Bad's abuse of Strong Sad isn't all that funny to begin with, but trying to drown his brother in a swimming pool during "Where My Hat Is At?" by encasing him in a block of concrete? That's Moral Event Horizon material right there.
Also the toon where Homsar is starving to death in the snow with his body caved in. As if that wasn't bad enough, it was the second to last (and last valid) toon.
Ear Worm: Quite a few, including "The System is Down!", "An Important Rap Song", and "One, Two, One, Two..."
Near the end of "Fall Float Parade," a giant Marshie Balloon feebly controlled by The Cheat rams into the platform where Marzipan and Coach Z are reporting. This became less funny when three days after the cartoon was posted, a Macy's Thanksgiving Day Parade balloon accidentally slammed into a streetlight, injuring two people.
Strong Bad losing it and blowing up the movie theater with a bazooka in the sbemail "the movies" is decidedly less funny after the The Dark Knight Rises Aurora massacre.
"Best Caper Ever", which is about Homestar floating on an ice floe through the Arctic as Strong Bad and The Cheat try to remember what happened, came out February 9, 2009, one day after 134 people were rescued from a freeflowing sheet of ice that broke off into Lake Erie. Because of this, the page title of the cartoon was "Total Coincidence! Not Intentional!".
"Attention Holiday Shoppers! Bubs Friday starts Thursday!" The last item in a "not Football TV" montage back on Thanksgiving 2007. Four yearslater...
In the 2008 Halloween cartoon "Most In The Graveyard", Coach Z dresses up as DJ Lance Rock from Yo Gabba Gabba. Matt Chapman has since become a writer for said show.
In Email 143, Strong Bad is talking about the different functions of Pom Pom's cellphone, from buying movie tickets to watching said movie to making his own. Nowadays, smartphones have internet access, Netflix and Hulu, and even 1080p video cameras.
Homestar: Strong Bad, your costume is making me feel (suggestively) loosey-goosey!
Strong Bad: Shut your face pile right now, or I'm gonna start feeling a little punchy-wunchy.
In this cartoon where Strong Bad is making fun of Halloween costume, there is one of a girl dressed up as Homestar Runner, which leads to conflicting feelings on the subject. Then Homestar Runner pops up and starts calling him 'sweetie.'
Mancuso's Older Brother from the first 2008 Halloween toon could count; the fact that he has a less-cartoony design than the regulars probably doesn't help matters.
Gelarshie from winter pool, particularly in a full-screen video.
Rescued from the Scrappy Heap: The King of Town was formerly regarded as a dull, one-trick pony and as such, was far and away the least popular character on the site. A combination of Flanderization and his own amusingly pitiful attempts to boost his status gradually endeared him to fans.
Shallow Parody: The 20X6 series. The Brothers Chaps aren't really all that up on anime, and it shows.
Stylistic Suck: Some (not all) of the Shallow Parody factor can be blamed on Strong Bad in-universe, who wrote the premise of Stinkoman based on one episode of one anime that he watched several months prior.
Tear Jerker: "Sick Day." You can't help but feel sorry for everyone in this one. Strong Bad is so ill that he's taken refuge under his desk and is rendered incapable of answering the latest email, The Cheat is sobbing in a bucket of puke, and Strong Mad is crying for help in his quarantined room. Homestar's ill to a delirious extent as well, though it's hard to tell if that's just his normal countenance or if it's compounded by his sickness.
An in-universe example in "Homestarloween Party"; everyone takes turns in adding to a supposedly scary story, and when it's finally Strong Sad's turn there's a robot and the Goblin. Strong Sad's addition to the story results in the formerly-human robot remembering its humanity, crying, shorting itself out, and crushing its two human grandchildren and the Goblin. "And no one lived." Everyone else is reduced to tears, and Marzipan tells Strong Sad that he's banned from next year's party.
Unpopular Popular Character: Coach Z. While most of the main characters besides Bubs and Homestar have difficulty putting up with his awkwardness, some fans find the same hilarious awkwardness endearing.
Also the King of Town.
The Woobie: Coach Z spends Decemberween trapping himself in his locker and drinking Listerine.
