I don't know if Kakashi reads it due to its popularity. I think it is because he really likes the story line [img]i/expressions/rolleye.gif[/img] (yeah, and I believe guys when they say they read playboy for the articles too!)

Actually, I have a theory. It starts off with Sandaime. In 83 of the anime, you get proof that Sandaime was a pervert, in addition to the fact he is incapacitated by Naruto's Sexy no Jitsu. I think he subconsciously molded Jiraiya into a pervert too. Of course Jiraiya overtook his teacher in that regard. Jiraiya taught the fourth. And the fourth taught Kakashi. I think it could be a causal relationship. Perhaps the first or the second was perverted too.

Basically it goes Sandaime -> Jiraiya -> the fourth -> Kakashi

In which case we should really be worried about Sasuke, Sakura, and Naruto. They may become perverts yet! Of course, I doubt the victim would be Sakura. She's too in love with Sasuke. I don't really think Naruto's Sexy no Jitsu and Harem no Jitsu are indicative of hentai behavior. He seems to criticize Sandaime for falling for his jitsus. That leaves Sasuke. Seeing as how the previous hentais were also very powerful, it could be that Sasuke is the next. He could be like Ebisu, Konohamaru's elite teacher, and a closet-pervert.
