If bringing sexy back resulted in a babe, perhaps you'd like to announce the news to your partner in a pair of these unconventional undies. The women at Smart Ass Thongs were thinking of you when they created their Yummy Mummy ($20) collection of thongs. According to their web site, the thongs are made of 90% nylon and 10% spandex, making them "perfect for tucking under growing bellies." Printed with "it's a boy" or "it's a girl" the thongs are certainly an unusual way to tell the results of your ultrasound.

Would you use underwear to unveil the information?
