I wouldn't sail this ship if I were you
1. Twattorama, 10:20 - 11:00, Channel 4. Each week, a random member of the public is chosen from the electoral rolls. The program proceeds to make the case, via a series of leading interview questions, selective editing and dubious use of statistics, that their subject is the worst person alive. Twattorama is the subject of a number of pending lawsuits, but remains inexplicably popular amongst people who are sure that they are not the worst person alive.
2. Polar souffle, 10:00-10:50, BBC2. A group of experts in different fields are locked in a room with a random selection of equipment. They have 50 minutes to prove the existence of the Arctic before the floor drops open and they are deposited in a bath of blue gunge. Note: the floor opens whether they are successful or not; this is a scripted part of the show.
3. MetaChallenge, 9:20 - 10:00, Channel 4. Teams compete to devise a new reality show concept. Each week they face a new challenge: coming up with the idea, pitching it to TV executives, recruiting subjects for a pilot episode, etc. Viewers vote for the concept they would most like to succeed. At the end of the show, the most successful idea is commissioned.
4. The Great British TV Dinner Cookoff and Jigsaw Puzzle Challenge, ITV, 8:00 - 10:00. Participants compete on a number of Saturday night-themed activities, including: cooking a meal for a family of four to eat on the sofa; finishing a 1000-piece jigsaw puzzle; getting the washing put away before bedtime; putting toddlers to bed in time to watch the program; etc. Anyone may compete. Indeed, the filming is almost entirely automated and one may choose the activities and participants one wishes to watch (there being many, many participants at one time) as well as acting as judges to rate their activities. As such, the program is something between reality TV and a really, really judgmental social network.
