Cool, it seems we all got into it through different means, I got into it by watching a video, All I was doing was watching TF2 SFM's when one came up as My Little Dashie, I ignored it for a few days until it kept popping up and I finally thought "Sure, why not"
I watched it, and was confused by it because it was only an SFM no real info on it, so I looked it up and I find a movie of it, and after watching it, I spent a few minutes sitting on my bed thinking about it until I finally thought, "Let's give the show a shot" and I was not disappointed.
