This song is “I’ll Be Your Man” by The Black Keys. Obviously it’s slightly shortened, but you get the gist. Now, no one ever accused Hung of not having any nudity on it. It is, after all, and HBO series (“Class + Ass = Emmys” — HBO), and the women characters get nude with some regularity. But considering that the series is about the size of its lead’s penis, it is sort of surprising that Thomas Jane never does full-frontal nudity, not even a short Dirk Diggler “I am a star. I’m a star, I’m a star, I’m a star. I am a big, bright, shining star. That’s right.” According to the show’s creators (Dmitry Lipkin and Colette Burson), that’s intentional:

Every woman who sees that penis thinks it is the perfect penis for her… Plato’s penis, the platonic penis…We haven’t shown it thus far because it’s in the mind for each woman who experiences it differently. … It’s the perfect penis for whoever encounters it.

Now, I don’t want to necessarily say this is bullshit, but it does seem to coincidentally result in the same rule you can find everywhere else on TV: female nudity is fine, male nudity is not. I don’t know if this is because most of the people who decide what gets on TV and what doesn’t are heterosexual men uncomfortable with their own sexuality OR if they just erroneously believe that is true of audiences (I’m inclined to believe the latter). But see the way Thomas Jane looks at you at the end of this sequence? Right into the camera? I guarantee if this show were about a woman this title sequence wouldn’t end that way.
