I've had a peculiar dice with numbers from 4 to 9... and since I wasn't really going to use it, I've decided to drill through it and make it into a keychain. And then I was so hooked that I've did that to more dice, until I got to the "I'm-not-going-to-harm-my-precious-polyhedrons-anymore" state... That's it, until I go and buy more dice to which I didn't attach yet and don't plan to use them while playing.
