Exorcist scene relived

I always thought that the scene in the Exorcist in which Regan is undergoing an MRI was one of the most frightening scenes in the film. I assumed the MRI's jackhammer-like sound was a Hollywood effect. It wasn't. I just had an MRI and it was SO loud, it was actually frightening. And that's with headphones on!

If our pug's head spins around in circles tonight, I'm outta there!
