Martin sets an almost impossible puzzle

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

Martin chooses the four digits of the his safe code based on counts of items (e.g. buttons) or body parts (e.g. noses, and testicles) featured in portraits and busts of Lasse which are present in the study. When Mark prompts him to explain how anyone else would know where to look for these digits, he initially seems stumped, but then spells out the clues across stacks of different-coloured paper, with just one letter on each sheet. However, he does not arrange all of the sheets in the correct order, leaving Simon a series of semi-anagrams to solve, to even figure out what the clues to the digits are. As Simon is unable to solve the puzzle, Martin earns no points for this task.
