If someone does not understand what's going on, Miura, author of Berserk from which the guy on the left originates, is a giant otaku. He stopped drawing Berserk for months because he got a hardon for Idolmaster lolis.

Quick disclaimer, it's actually more of a meme than anything. His art has so much detail that drawing a single page can take more work than some manga take for whole chapters, it's much more likely the reason he slowed down his publish rate is so he wouldn't drop dead in his desk, which apparently used to be a real problem when the chapters released more frequently.
