person 1: I was accepted to every school in the Ivy League, but didn't attend, as I have no need to childishly prove myself to the world. I attend El Generico State University, because it's just as good, if not better!

person 1: I also won the Nobel Peace Prize for 2006 last month, but chose not to accept it, as I feel it's a completely overrated award. I told them to give it to Muhammad Yunus and Grameen Bank instead.

person 1: Miuccia asked me to walk in her show at Fashion Week, but I declined, as I only strut the runways for Eddie Bauer. Why would anyone want to wear Prada anyway? I told her to use Gemma instead.

person 1: Well, I must be off! President Bush wants me to negotiate a truce between Israel and Hezbollah.

person 2 (out loud to no one in particular): Why do I talk to her?
