To tell you the truth, I'm not fond of the phrase "super husbands". But I really like the rest of it. If you don't mind manipulating the design, I'd love to see the vertical style half'n'half arc/shield on top with the arc inside the shield version faded in the background, and no type at all.

If that's a problem, I'd be satisfied with the current version without the words. My car needs more bumper stickers! Between the two Doctor Who stickers, the Cthulhu election sticker, and the quantum lolcat sticker, I've been really enjoying having people ask about my bumper stickers.
