My Google-fu, let me show you it. (Dinosaurs, in German, which I do not speak)
So there's a cheerful The Demon's Lexicon chat going on, and someone mentions dinosaurs and a comic, and that it was in German. Armed with one keyword, Google Translate, and Google Image Search, I find the very comic collection she was thinking of.
vandulocity: although... can you imagine what would happen if you had two demons fighting over the same body? oh dear...
Azz: That would possibly be worse than a body's own soul and a demon.
Playwithfyr: do you think its ever happened?
vandulocity: which? the two-demons-vs-one-body?
Playwithfyr: it would be strange
Azz: it would be really strange
Azz: I bet it has
Azz: like, once
Playwithfyr: it probably caused some massive human event
Playwithfyr: oooh, maybe it wiped out the dinosaurs
vandulocity: thats what i was thinking
Playwithfyr: when two demons possessed one T-rex
Azz: and both demons were in such fucked-up shape after they came back (or maybe they just like died) that they decided ok never again
vandulocity: does that mean there were dinosaur magicians? :)
vandulocity: hee! dinosaurs with pointy hats and robes! drawing summoning circles! ahahaha
vandulocity: yup. that's totally how it happened
vandulocity: where are all the artists when you need them? ;)
Playwithfyr: how dare they have other commitments
vandulocity: i call it shocking
Playwithfyr: Ravel! Can you draw?
ravelqueen: not at all
ravelqueen: like absolutely not, stick figures look weird when i draw them
vandulocity: we need a pet chatzy artist ;)
ravelqueen: but, there is this one funny comic, where there are funny looking dinosaurs...and i may remember one with party hats
ravelqueen: let me search
vandulocity: oh, yeah, i think i know the one
ravelqueen: really? which one are you thinking about?
vandulocity: i have no idea what it's called, all i remember are bright green dinosaurs and that i think it's written by a guy called ryan...
Azz: Dinosaur Comics
Azz: Ryan North
vandulocity: that would be the one :D
vandulocity: azz, do you actually knoweverything? :)
Azz: No, but with Google at my fingertips, I can almost make it look like I do!
