Rob's toilet bowl night-light
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Rob brings in a light for the inside of the toilet bowl, so that one doesn’t have to turn on any lights when visiting the bathroom in the middle of the night. Greg awards Rob first place, because he is a middle-aged man with a swollen prostate, and can therefore relate to the experience of having to get up in the middle of the night to pee.
