You see, you see!

Aaron Swartz: "On February 21, 2003 on watched my first episode of Buffy the Vampire Slayer (6x09). I'm not sure why I did, or why I chose then, or why I chose that episode, but I do know this: I was blown away. I spent all day thinking about it, unable to get it out of my mind, craving more. Since then, I have watched every aired episode of Buffy, spinoff Angel, and creator Joss Whedon's other show, Firefly, from the beginning, in order. "

This is exactly what happened to me, but fortunately it happened a few years earlier so I could at least experience most of S5, 6 and 7 in realtime. (Via Tom)
