Fern theorises on bifurcated poo

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

To fulfil her sign about eating enough fibre, she requests the sandwich she'd be having for lunch. She breathes deeply, to fulfil the 'Breathe' sign, and sits on all of the seats marked with 'Warm your bum'. She is unmarried, so cannot obey the sign telling her to leave her husband. She runs as instructed by one of her signs, but is unable to fulfil the instruction to poo in her pants, as she thinks her poo would come out of her costume. She goes on to theorise that it would be bifurcated by the part of her costume that runs between her buttocks. She manages to fulfil the instructions on 75% of her signs, earning fourth place.
