It's best to watch in order from the beginning. You can pick up the Red vs. Blue Season 1 DVD at Gamestop or Buy Online at the RvB website. Another avenue you might try is taking a look at this link...

It's the Season One rolling archive. Right now you're in luck, because it's rolled back to the beginning of the season. Right now you can download episodes 1-6.
The humor is right up your alley, Mac! You're sure to enjoy it.
Thank you for joining the RvB cult. We'll be needing your current home address so we can send a missionary by your house, and we can instruct you on RvB philosophy and how you can be a born again RvBian. Yes, through RvB all things are possible. Won't you let it teach you the way to a better life?
Just joking. I got to the bottom of my post and realised that it sounded like I was converting you to some kind of religion. Hence the above paragraph.
