When people steal your jokes, your haircut, or your music, the instinct is to fight back.

It's hard, sometimes, to know how. Anger can be so bestial.

But as Kotaku reports, Jonathan Coulton seems to have lighted on an excellent wheeze.

Coulton, you might remember (or not), created a cover of Sir Mix-A-Lot's "Baby Got Back," which then seemed to appear in all its blessed entirety (lyric changes included) on the popular musical psychology show "Glee."

He doesn't seem to have got very far with appealing to such exalted entities as the producers of "Glee" or the lawyers of "Fox."

Indeed, he says he was told he "should be happy for the exposure." Those with remaining hearts might wish to point out that the only exposure came from the media, rather than from "Glee," which didn't actually credit him at all.

So Coulton has foxily tossed up on iTunes his own version of the song and titled it "Baby Got Back (In the Style of Glee)." He terms it "my cover of Glee's cover of my cover."

Hee. Hee. Glee.

Because all indy artists like Coulton have a soul, he is sending all the proceeds of this fine piece of music through February to charity.

It seems, though, that Coulton feels less charitable toward the "Glee" people. For he has placed a very subtle image of himself on iTunes offering the "L" sign upon his forehead.

I am fairly confident he is not expressing love.
