Somebody in front of us in the cinema collapsed when that happened.
Being made of sterner stuff, we survived but we definitely weren't in the better of it.

And then there's the exorcist...

And Jaws! When that shark came right up to the edge of the boat just missing yer man's leg my dad quickly pulled his legs in towards his chair. I damn near died laughing.

We must all be a little touched to seek out stuff that's going to scare the living daylights out of us!
