"Paris and Nicky Hilton? Those girls will show up to the opening of a phone book. It's like a big joke"

This quote by Rachel Perry is a funny method of expressing her opinion of the Hilton sis, Paris and Nicky. She suggests that they are so excited to be seen in public that they would go to any occasion, no matter how irrelevant. She implies that their existence at events is a joke, as if they are just there for the sake of being seen. This quote is a commentary on the culture of star and the lengths that some people will go to in order to be seen and acquire attention. It is a funny way of expressing the idea that the Hilton sisters are willing to do anything to be in the public eye.
