Blister packaging: as pleasant as it sounds

I bought a wireless headset for my Xbox 360 and it just got delivered to work; I'd very much like to plug it in so it's charged for getting home, but I can't get the damn thing open.

I really hate the space devil packaging they use to store videogame accessories these days. I realise it's possibly helpful as an anti-theft device - you can't pop the container open and steal the goodies, and there's a tag in the box itself - but I'd like to be able to get the thing I paid for without shredding my fingers trying to get into the box.
