Chloe Spelth was a contestant on the Grub Tank (see Episode 86) where she pitched the idea of 'Friendship Cuffs' to the experts. The Friendship Cuffs are a pair of handcuffs, set to a timer that literally bind people to potential friends to give the chance for friendship to bloom. The least amount of time the cuffs can be set to is seven days, research showing this is enough time to foster a friendship. Chloe produced a knife during the taping of the Grub Tank, and this combined with her unpleasant odour prevented Greg and Ben from investing in her idea.
