Coming in at an auspicious number 69, Colbert's ranking on the list was explained by Maxim:
Democracy isn't always pretty: Sometimes it's downright handsome. With a massive write-in vote campaign, the Colbert Nation proved they're not only loyal but also incredibly horny.
Of course, we couldn't help but think Colbert's cause was helped by the fact that our own Arianna Huffington recently bestowed upon Colbert the title of "Honorary Woman."

In special recognition of his continued efforts to bring to light the issues, both real and imagined, that face women, and generously putting a male voice to their struggles, which is far louder and therefore more convincing than a female one, Stephen Colbert, with the approval of most of the women around the office, is conferred upon the title of 'Honorary Woman' with all the honors, privileges and nearly the same rights as men.

Perhaps this was the push the "Report" host needed to help him across Maxim's notorious gender barrier.
