You write about things of importance to you. And it's gotta be for real. Do I think about my dick? Oh, yeah, all the time. If I think about it all the time, I got a right to sing about it. If I wasn't thinking about it all the time but thought, "It's time to write a rock song, I'd better mention my dick," then I wouldn't even be able to say "dick" right. Besides, it's an ecological line. It's not, "My dick is all bad, motherfucker, wickety wackety woo." It's nature-oriented. [Pauses, looking serious, then laughs] It is!
