1. Give it to your missus as a jewelery bag
2. Cut 3 holes in the back of it for your little dog / cat's legs and tail and fasten. Now you've got an instant diaper to stop the little bastard crapping all over your house
3. Use it to store the stock fans that arrived with all your PC components that you can't bring yourself to throw away.
4. Use it to store component instructions (I actually do use my one for this)
5. Use it to store random lists.... of which this really is one
