Holly Madison and Bridget Marquardt do what they do best, party and dress slutty.  The two hosted a party over the weekend for National Lampoon’s Great American Run.  Wanna know what it is? Bennett Media Worldwide states:

“National Lampoon’s Great American Run combines the always fascinating appeal of exotic cars with action/adventure stories, making this special interesting and gripping for audiences,” 

Basically it’s a reason for playmates to dress sluttish, drink it up, and get nude; I mean just check out Heather Rene Smith’s costume…err body paint.
