those little apple logo stickers, where'd you put yours?

I first thought I could put it on the back windshield of my car. But after getting back there, I realized it was not "reversed" and suitable for placement on the inside of the windshield. So I trashed the idea. Still looking for other cool places to put mine - I've got two from my mac mini purchase and two from my iPod mini purchase.

Where did you put yours?
