Truly awesome
As a geek who's played D&D a fair amount of times, I find this series hilarious (especially because it contains stuff that the kid who DMs all the time would literally beat the hell out of us for doing, but we wish we could do it anyway).
Yeah, anyway, to help you out on the next one, here's a tip: take your microphone and record nothing for, like, ten minutes or whatever. Then put the recorded silence in a separate layer that goes throughout every scene. This will make everything sync up throughout the episode.
I really can't wait for #6.
