Mike, Matt, and Ryan made an appearance at Georgia Tech last week. They brought along Flash 5 and animated a brief clip of Homestar walking and talking. The current Quote of the Week ("talk and mouth move") was recorded for this appearance. They showed the Bonus Strong Bad Email for the upcoming 5th disc of the DVD, and several other shot clips or images never seen before. They answered questions at the end of their 25-minute presentation (and did some voices too, of course).
(Transcript is a work in progress. The transcript and video contain mature language. Edit 5/4/07: Censored transcript is up.)
For those who still haven't seen it, you really should. If you want to watch TBC do animation in progress (including the "doink"), the bonus e-mail, a cartoon they did for one of TMBG's songs, hear Matt put down Happy Tree Friends in a nice way, impromptu Strong Bad, and a mention about who currently has a baby on the way, this video is for you.
