Rich And Joe And Mark's Perfect Ten

This week we come up with the sport of the future 'Blind Formula 1' and all feel a little dirtier afterwards and Joe is kind enough to share his toilet destroying techniques with us, which also leaves us all feeling a little dirtier afterwards. As always you can send us questions or themes to thisisdumbproductions@hotmail.co.uk or tweet @rakennedy, @markrharding or @hardingjoe
