I just wrote the joke. I didn't make the character or the money windmill. Obviously bitsquirrel is an invention of Joey D. Though, I applied a modification of bitsquirrel that make them gliding squirrels.
You are free to reuse them as you like. They're public domain.
I made the money windmill, and I was tickled that you wanted to use it. That said, I don't think it worked well in a comic, and here's why:
Symbols and memes are everywhere on the internet, and they mainly work well because they pack a whole lot of information into an immediately recognizable and portable package. The symbol is already the punchline.
You can make comics which use these symbols, but they're bound to end up seeming weak, because they don't have any particular reason to exist. If we recognize the symbols and smile at them, we don't need a comic to remind us of it-- you can just show us the symbol and we'll smile. If you can show us a very original story, or character, or ironic situation, and incorporate a symbol into that, we'll fall out of our chairs. But if you rely on the symbols to carry the weight, it'll fall flat, even on those who understand what the symbol means.
When you're writing jokes for an in-group, you're bound to come up with a lot of crappy jokes for this reason.
My advice (FWIW) would be to not worry so much about making jokes about bitcoins, and focus on making jokes that people who like bitcoins would find funny. If you can make a few nods to the bitcoin community in the process, all the better-- but bitcoin itself isn't that funny.
Also, PS, Synaptic: you're a huge douche. Fuck you bloody with a sharp stick.
Y'know one of the things I've learned since interacting with Internet regulars, including personal friends, is that those who use the epithet "douche" are usually prime specimens.
It just seems as though people who use the classics like "dick-head" or the time honored "asshole" are just of a higher caliber of person than those who use "douche." I mean truly, calling someone a douche is well...kind of goes right along with the personalities that most people consider..."douchebags."
"Douche" is just that sniveling, moist, flabby, pathetic choice of an insult. Like, the insult of choice among...lower people.
Anyway...I mean this is obviously non-topical, but since you paid me the distinct delight of the insult I'd thought I'd share that small semblance of an epiphany with you.
