The cat has long since been let out of the bag on this one, largely thanks to a series of YouTube videos in which referees are shown placing a shiny metal thing into the palm of a wrestler as they lay strewn on the mat.

But it warrants a mention because of the undeniable skill involved in pulling it off.
