Sara Underwood — Babe of the Day
Whether you remember Sara Underwood as host of G4's 'Attack of the Show' or as Playboy Playmate of the Year, the constant is that you definitely remember her.
These days Sara is keeping her talents on display via Instagram, where she frequently posts jaw-dropping pics of her wearing everything from very little clothing to no clothing whatsoever.
Based solely on her IG, it looks like she's a big fan of getting in touch with nature... and herself. In short -- the girl knows how to Instagram. She's also pretty good at deflating a tube, as you can see in the video above.
