How much can one little secret hurt?

It is just one secret...just one big, dark, hidden secret. Let's play a game and find out. The catch is - you won't find out what task you'll have to complete until you've already entered and told me your secret. You won't even get a hint...until it is too late.

Follow the instructions in this clip to enter and you'll have no choice but to obey...or find your secret spilled to the whole world.
