Origami fairy boots.

One of my fellow firefighters made a pair of these last summer, but was very secretive as to how she went about it. Today I set out to learn this frivolously delightful trick, and now I'm divulging it to you--so's you can be all suave-like the next time that cute waiter compliments you on your shoes.

This is the best way to leave a tip that I've ever seen; use a dollar or a five for the boot and slip any extra change inside. (Instructions can be found here and are user-friendly to the origami impaired. My first boot took me about three minutes.)
