Holly Madison Had a Wee Bit O’ Fun on St. Patrick’s Day (PHOTOS)

When St. Patrick drove the snakes out of Ireland, he probably didn’t realize that his act of heroism would one day lead to former Playboy Playmates partying with the vertically challenged, playing beer pong and sucking on green lollipops, but we suspect he’d approve anyway. He just seemed like he was cool like that.

Former Girls Next Door girl Holly Madison observed St. Patrick’s Day the way it was intended to be observed at O’Sheas Casino in Las Vegas on Wednesday—with short friends, tall drinks, and cleavage. Lots of cleavage.
