When they show an episode of Mythbusters, they tell viewers to check the online aftershow videos where they answer viewer questions about the episode.
I’ve gone online right after the broadcast ends and they’ve already got the videos up. Are they actually standing by in a studio during the broadcast, receiving email questions, and taping their responses so they can post the video immediately? Or is there a test audience that sees the show earlier so they can ask questions and let them pre-tape the aftershow video? Or do they just make up some questions that they figure viewers are going to ask?
