1. Garfield comic book! The protagonist is wildly popular because readers can easily identify with him.
2. Cookbook? Cool kitchen-gadget/torture-device? Super duper plunger measuring cup? Think of the possibilities!
3. Hats! Ear-flapped, sans-flap, pompom, fez, beret, ferret.. Gloves are good too; my fingers are on the stubby side.
4. Music! Be surpriseful. Be eclectic.
5. Books! Books are fun, by definition.
