For anyone else who hates stickers as much as you and I do, I found the perfect tool for removing them: the plastic toothpick from a Swiss Army knife.

The toothpick has a very flat tip that will go right under the corner of a sticker and let you lift the corner - and then the rest of the sticker will pull away easily. At the same time, the toothpick is soft enough that it won't scratch whatever surface the sticker is on.
