There's evidence than Strong Bad and Strong Sad got along really, really well. So why is Strong Bad so abusive? Listening to the Marzipan Answering Machine 17.2 and seeing one of the Decemberween videos, you realize Strong Sad enjoys being sad and put upon, which means Strong Bad is abusive because that's what Strong Sad wants.
I was watching "stupid stuff" again, and it dawned on me: Kevin Grumbles sent Homestar a "HRemail"!
In the Strong Bad Email hremail3184, Strong Bad destroys his Lappy through a fiery explosion. Some tropers may make angry comparisons to "retirement", but if you think about it, a showstopping finale is also what laid the spirits of the first two computers to rest in that sbemail, which is what happened here too. ~ Old Man Ho Oh
Fans of Homestar Runner have always wondered why Strong Bad hasn't taken off his mask, even going so far as to email "him" over and over. While he says it's actually his face (sure enough, it caused him immense pain the one time he tried), there's also a real reason in real life: Lucha Libre wrestlers DON'T TAKE OFF THEIR MASKS, EVEN OUT IN PUBLIC. (For the wrestler, it's a flamboyant and special, but effective, part of their identity).
In the song These Peoples Try To Fade Me, Coach Z says he's "so old-school they tore the school down". While it may sound like a typical Coach Z line, it making absolutely no sense, this line actually does. Basically he's more old-school than old-school.
Remember that Teen Girl Squad episode where Tompkinis was playing an original Gameboy and said that "she got Bowser on the ropes"? Well a few people are saying that Bowser didn't appear until Super Mario Bros Deluxe. However, Bowser was also in Tetris Attack and Yoshi Cookie. (Gameboy versions)
Why did Bubs resort to violence to get Strong Bad to take back his story of "Orginal Bubs"? Because, as Strong Bad himself later confirmed, Strong Bad is a reality warper whose stories and ideas become real at random, and Bubs didn't want to be replaced by Strong Bad replaced actor parody. And it's a good thing he did, parts of that story that weren't shot down became real, from there being several Kings of Town to Onion Bubs.
How did Pom Pom come back after getting killed? He previously got a 1-Up by beating the crap out of Strong Bad in the Strong Bad Email "pom pom".
Ever notice how the clips from Dangeresque 2 in the email 'stunt double' have an actual instrumental soundtrack, while Dangeresque 1 only has 'doot-doos' sung by Strong Bad (save for the credits theme)? That's because Dangeresque 2 is the sequel! Of course it would be improved compared to Dangeresque 1! Dangeresque 3 continues the trend with its soundtrack, having only one scene near the end contain the classic 'doot-doos.'
In sbemail206, we get a trailer for Dangeresque 4 / 2 = 6, in which there are two Dangeresques and two Dangeresque Toos. What does that have to do with six? Two Dangeresques (1 + 1) + two Dangeresque Toos (2 + 2) = 1 + 1 + 2 + 2. That equals 2 + 4. But that equals...
In sbemail84, Strong Bad says that Southern accents are hot. In Marzipan's Answering Machine 17, he calls Marzipan as "Sharpdene," the "new girl," who has a Southern accent.
It may seem strange that Strong Bad and Senor Cardgage look a lot alike, yet aren't related at all. However, keep in mind that Strong Bad used to admire Senor- he maybe put on his trademark mask and boxing gloves to emulate Senor Cardgage! Although this begs the question as to why he hasn't taken them off yet, seeing as he doesn't care for Senor anymore... or why he still looks like he does now in the sbemail high school.
In A Death-Defying Decemberween, there's this hot drink that two of the characters are seen drinking called Hot Jones. At first, it looks like a cup of hot milk with what look like red sprinkles floating in it. Then, somehow, some time later, you'll find out that "jones" refers to a now-rare slang for heroin. Whether that's a coincidence is up to you.
Some of you veterans may remember Buiscuitdoughhandsman, the 'guy' first suspected to have stolen The Poopsmith in the Strong Bad is in Jail Cartoon. At the end of Strong Bad Email #145 myths & legends, Stong Bad mentions "startling new evidence in the Biscuitdoughhandsman conspiracy". An easter egg shows an anonymous interviewee (who's definitely not Coach Z) telling he found a "severed hand" in the locker room and holding what i can only deduce is a piece of unbaked biscuit dough with a bite taken out of it. Anybody else think the King of Town might have murdered and possibly eaten Buiscuitdoughhandsman?
In "fan club", Strong Bad refers to Strong Sad heading the Deleteheads, a fan club devoted to Strong Bad and Sbemails, as a bit of "Stockholm Syndrome-esque irony". But considering that Strong Sad still runs such a club even after Strong Bad has continued to abuse him (sometimes in horrific ways like chaining him inside a filled bathtub), there may be a disturbing truth to that.
Even more disturbing: in "A Decemberween Mackerel", Homestar Runner and Marzipan are shown singing carols to Strong Sad who is once again chained up in a filled bathtub (presumably again by Strong Bad). Strong Sad shrugs off the inevitable hypothermia as something he's accustomed to, and neither Homestar nor Marzipan do anything to help him out aside from singing carols to "cheer him up".
An offhand gag in one of the Hremails shows Strong Bad walking around in what appears to be Strong Sad's severed feet, which brings disturbing implications if not for Negative Continuity. It's made all the more disturbing by the squishy noises they make with each step and that he refers to them as "foot pelts".
However, see Fridge Brilliance in that Strong Bad may just be doing what Strong Sad wants.
While Strong Mad is The Brute, Strong Bad is tiny. Strong Sad, who is of average height and heavy, could more than likely physically overpower him if he tried. The fact that he doesn't is a Fridge Horror moment itself. He's either so thoroughly cowed by Strong Bad or so genuinely despairing (or both) that he doesn't even try to fight back.
Even the Fridge Brilliance above that seems to mitigate this on the surface could have some horror of its own: Strong Sad's continued use of medications and personal punishments for Strong Bad are at odds with the idea that he likes being unhappy, but mostly when this comes up he more accurately expresses distress about not being unhappy. He could easily have cherophobia- the fear of being happy, which is often motivated by the belief that allowing yourself to be happy for even a moment will lead to something tragic happening. When compared against how he seems to consider horrible life circumstances the status quo, and the disappointment he received some of the few times he got his hopes up ("big white face", "concert"), this is sadly very plausible.
Just what exactly was that evidence Bubs was burning in "Bug in Mouth Disease"?
Most likely it was something involving organ trafficking: he claims to have "a fresh pancreas" for Homestar in the cooler marked "Exhibit B", and in episode 2 of Strong Bad's Cool Game for Attractive People, you need Strong Bad to sell Strong Sad's pretendix on the black market (run by Bubs, of course) in order to get a Plot Coupon.
