Last night, Olympian, model, actress, and activist Aimee Mullins schooled Stephen Colbert on disability and prosthetics last night. Of course, there was also a proposed Boob Olympics.

There was something rather endearing about Colbert's wide-eyed surprise at Mullins' accomplishments and twelve pairs of legs, even if she probably already knows how hot she is and doesn't need Colbert to "discover" it. Still, it's hard not to be in awe of her.
