In this extreme version of the task, one contestant is first instructed to follow a chain of tied-together shoelaces. They then discover a massive tangled web of shoelaces filling a room at the end of the chain, and are instructed to untie all of them as quickly as possible.
In this much less extreme version of the task, one contestant is presented with a bathtub which is half full of tied-together shoes, and is asked to untie all of the laces.
