Sarah's 'Do Not Disturb' sign
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Sarah brings in her own personal 'Do Not Disturb' sign, which she takes with her to hotels when on tour, to ensure that no-one ever tries to come into her room. Although he enjoys the rage behind her prize, Greg awards it fourth place.
