Grumpy set up the course of the tournament days ago so that it would be ready. There were many obstacles along the way. Most would make it if they were smart. He did want it to be impossible. But it couldn't be easy either. It had to test them on every level: strength, courage, wisdom, loyalty, speed, determination, endurance, flexibility, power, adaptable, and the ability to think under pressure. The first test was a puzzle: Design a storage system that encodes 24 information bits on 8 disks of 4 bits each, such that:

Question: There is a story that a man and not a man
Saw and did not see a bird and not a bird
Perched on a branch and not a branch
And hit him and did not hit him with a rock and not a rock.

[How is this possible?]
