Bittorrent them, Sike. I posted working links up above, but you can find more at sites like
SuprNova.org and
tvtorrents.com. As long as you aren't on dial-up, you should be able to use a fast bittorrent client (like my favorite
BitComet), and use the links on any number of bittorrent hash sites to be able to download extremely high quality copies of the episodes, and catch up to the show at your own leasure...
