Yo dawgs, here's some real street wank for ya UP TOP
On The Comics Journal message board, a poster calling himself blackfoot starts a thread asking "what is art theft anyway?"
It quickly becomes clear in the course of the thread that elsewhere, on Comic Con's message board Blackfoot had criticized the art of one James Bogner, Bogner invoked Ebert's Law (this is what "Ebert's Law" means), asking Blackfoot if he could draw any better, and Blackfoot responded by taking a caricature of Mick Jagger Bogner had drawn, cropping it, and using the "spraypaint" tool in MSPaint to shpritz an afro on Mick. All this becomes revealed quickly on the first page of this tcj.com thread, yet despite this, the TCJ regulars keep referring to Blackfoot "copying" or "tracing" the art, and trying to explain why this isn't good as though Blackfoot weren't obviously a troll.
On page 2, Steve Hogan and others identify Blackfoot's "drawing" for what it really is, yet James Bogner continues to take Blackfoot seriously. Others try to give Blackfoot drawing advice, so Blackfoot on the middle of Page 4, posts more of his mad skills in the form of a couple of hilarious drawings of cartoon fish, then on Page 6 Steve Hogan finally spells it out for everybody by explaining that Blackfoot's "drawing" really is just Bogner's drawing slightly modified in some computer program.
At THAT point, Blackfoot's sole defender, "Darren Tweage" joins the board just to insist Blackfoot's version is better and to ask the musical question "Is it stealing if some one improves it."
Then Blackfoot reappears to bust a few rhymes: "I ain't gone give up, No I ain't gone let up. No I ain't gone shuddup and ain't gone never let them haters get to me. Oh, no-no, They'll never get to me. I ain't gon' give up, no I ain't gon' let up. No I ain't gon' shuddup." (this goes on for a few paragraphs.)
Finally, on the 7th and last page, "Darren Tweage" mysteriously signs his post "Blackfoot" (because it wasn't painfully obvious that he was a sockpuppet before) and the thread is quietly locked.
I don't know, I found it funny. Posting to Fandom_Wank because I figure a drawing of Mick Jagger is fan art.

(for your edification: Here is Bogner's original Mick caricature And here is Blackfoot's "version". You really need to see these to understand how funny the TCJ thread is.)

(Many thanks to anne_noonlight for finding the Ebert's Law post for me)

EDIT: In another thread Blackfoot asks the board admin why his thread was shut down and assures everyone he isn't Darren Tweage: "Darren Tweage = Blackfoot, No! It want fly. " (Thanks to the anonymous commenter for pointing that out.)
