J. Scott Campbell's never been the most realistic of comic artists, and that's part of his charm. But the notorious pranksters at 4chan have taken issue with the way he posed Mary Jane Watson on the cover to Marvel's The Amazing Spider-Man #601. You'll need to click after the break to see 4chan members acting out the contortions.
This brings up a broader point about cartooning: Since their inception, comics have largely strayed away from realistic depictions of characters, be they humans, anthropomorphic animals or anything else. While Campbell's poses might not be anatomically realistic, part of his style/aesthetic/appeal lies in that bending of reality. Having real people act out some of the exaggerated poses of Campbell, Rob Liefeld or Jack Kirby would show how unrealistic they are ... but then again, that stylistic exageration is what makes illustration different from photography and part of the appeal.
That out of the way, seeing people act out Campbell's poses below is engrossing.
