Hulu

Z and I are huge fans of hulu.com.  It's really our main source of entertainment and it's completely free.  This website is where I got hooked on 30 Rock because I can control when the show is on!  We've recently found lots of great documentaries including "Kicking It" about the Homeless World Cup, other documentary shorts, and dozens of national geographic feature films about sharks, wolves, and bears.  Oh my!
