Movie Sample in music
 

Seeing as how it's the right time of the season, my band is looking a for a new intro for our set.
We like to sample sound bits from movies, tv, etc.
What would be a really scary sound from a horror movie?
It could be a quote, or even a theme song. Just something to kick off our show in a scary way.
we play hardcore music.
So far, we've been thinking of the classic, I am the devil and I've come to do the devil's work.
but i'm honestly stumped, and feel like there is so many better ones. I just can't think of any right now. PLEASE help.
thanks.

Tubular Bells from the Exorcist would be pretty recognizable

The shower scene 'stabby bit' from Psycho.I have it as my ringtone!
