Reply to Halloween costumes?

We're celebrating halloween this weekend here in sweden, and I'll be djing on friday - who can give me some original costume ideas? I'm all out of them - since I'm a hockey freak I always used to dress up as a hockey player but it's getting old now Might not have time to order a costume online so DIY would be preferred.

But 2 things:

1) Don't tell me to make a Deadmau5 mask because that's the most unoriginal thing I can believe of
2) I need to be able to use my headphones - on top or underneath the mask!
