Have you guys seen this video of Paris Hilton on David Letterman? It is so funny! And not even the part where Paris is all "I love Benji Madden and we are going to live happily ever after for ever and ever." Really, the best part is how Dave reacts to her. If you look closely you can almost see the little birds and bubbles swirling around Paris' vacant head. And I'm pretty sure Dave can see them, too.
