Julie sets a puzzle which forces Mark to remove his clothes

Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.

After determining that Mark will be present when someone tries to solve her puzzle, Julie decides to use his body as the delivery mechanism for her clues. She writes at least three of the digits to the code on different parts of his body so that he will be forced to remove his clothes as the puzzle is solved. As Eva solves her puzzle in the closest time to 20 minutes (13 minutes and 48 seconds), Julie wins this task.
