On the show this week, the latest exploits of young whippersnapper Justin Bieber, a look at winter sports reality series The Jump, so-called Twitter 'trolls' and some wet toilet paper. Plus, Jake Yapp squeezes an entire episode of Take Me Out down to 94 seconds, Doug Stanhope looks at Discovery Channel's Skywire Live and asks why nobody is interested in his own death-defying acts, and Philomena Cunk explores the world of computers and asks what videogamers did before they were invented.
