Munya's fidget spinner
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Munya brings in a Golden Snitch (object from the fictional game of Quidditch, from the Harry Potter universe) fidget spinner, which - he makes the mistake of mentioning - cost him £15. He says the item has emotional significance because his strict Christian father would not let him watch Harry Potter. Despite the fact that the item does not qualify within the rules of the task, Greg decides to give Munya an opportunity to lie to him about how much it cost, after hearing his sob-story about having to watch Harry Potter in secret. Munya then says that it cost him £21, and Greg awards him joint third place, with Fern.
