Nikki has a late realisation
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Nikki is shown eating several sprouts before finally declaring that she cannot eat any more. She rereads the task and realises that she didn’t actually have to eat any of them, and breaks down with laughter. Ultimately, Nikki eats eight Brussels sprouts. While estimating the total sprouts eaten, she declares that “no-one is as crazy” as her, so places her final guess at 13 total Brussels sprouts eaten. As a total of 38 Brussels sprouts were eaten, Nikki comes last.
