The whole article is good reading, but here's the "money quote":
Playboy: "You are aware that you're a sex symbol, right? Some might even call you a DwILF."
Dinklage: "DwILF, as in Dwarf I'd Like to Fuck? That's very clever. Honestly, I think there's an irony in all of this. I take it with a grain of salt. They'll say, "Oh, he's sexy," but women still go for guys who are six-foot-two. It's nice that people are thinking outside the box, but I don't believe any of it for a minute."
