I must disclose that this is the only parts of the show that I've ever seen either, but CS doesn't appear to be much of a strain on the brain. Pick a star, pray that they're right. Do it 12 more times, roll credits. They don't have to answer the questions, or do anything else, except for the interviews at the top of the show.
Then again, I've only seen those four clips, so there might be something I don't know about. What am I saying, "might"...
