Ooh you must be talking about Welcome to the NHK. That dude does all kinds of stuff. Locks himself in his room, tries to go outside to get a job, fails, meets a girl, fails, meets another girl, tries to kill himself, fails, becomes an otaku, fails, tries to become an otaku again, fails. See all kinds of stuff. except he doesn't play with himself, if that is the stuff you are talking about, he does not do that.
