Of all the moronic, dimwit, tunnel-visioned, agenda-driven, academic, peer-pressured reasons to clamor and claim (for 40 years now) that "painting is dead," this is probably the only good reason to kill painting.

Warning: The link above is rather gross, as it depicts artist Keith Boadwee in the process of "painting" via the use of his asshole. This is definately "mixed media."

And this artist may be a close second.
