Ah, the pilot. It has provided me some of my favorite moments. I didn't see it for a LONG time, and when I finally got ahold of it, it was magical. Although it is probably the saddest episode, especially when you're familiar with the series before hand. For example, when Bloo tells Mac, "Don't worry, buddy, I'll be right here. I'm not going anywhere," I was just...
, because I knew the inevitable outcome. Bloo thinking Mac had abandonned him was pretty depressing too (in a good way), because he just wouldn't talk for a good portion of the time. And Bloo not waggling his lips about something or other is slightly unsettling.
