In one of my random Wikipedia wanderings, I came across a neat web tool that calculates an actor's "Bacon Number", or degrees of separation they have from Kevin Bacon. Some of my favorites:

Ronald Reagan: 2
Ronald Reagan was in The Young Doctors (1961) with Eddie Albert
Eddie Albert was in The Big Picture (1989) with Kevin Bacon

Arnold Schwarzenegger: 2
Arnold Schwarzenegger was in Twins (1988) with Maury Chaykin
Maury Chaykin was in Where the Truth Lies (2005) with Kevin Bacon

Jon Heder (Napoleon Dynamite): 2
Jon Heder was in School for Scoundrels (2006) with Angela Frye
Angela Frye was in In the Cut (2003) with Kevin Bacon

If you haven't heard of Last FM (http://www.last.fm), you should check it out. It's a free service that tracks all the music you listen too and gives you statistics and recommendations based on what you listen to. You can also post the last few songs that you've listened to on your website, like so (look to the right). Looks like Jimmy Eat World still holds the record as my favorite band.
