Joe and Sian play long-distance catch
Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!
Joe and Sian pretended to be in various locations around the planet, with Joe pretending to be in Rome and 'space', whilst Sian stood next to Romesh Ranganathan in a single location, with Romesh claiming that they were in countries including New Zealand and Malaysia. They only actually covered 466 miles.
