Kojima sure is one pervert fellow - I actually went to the locker, opened one of them, looked the poster from the 1st person view, and called otacon - and had some fun
What makes Kojima pervert, is the fact that the scene can\'t be a mistake, not a stupid bug, not a co-insidence, but a scene done on purpose. There was some coding to do to get Snake do those faces, and someone had to record that voice reading the text. Kojima planned the scene, and actually had to write a history to it, and then let the coders and staff to do it.
Even more fun is, that you can call Otacon endless times, and you can every time see Snake doing \'it\' with himself. Makes you think if Snake is a superhero after all, just aided with a name wich suits the \'superpowers\'...
