The first film to make me cack my undies was "The Fog" - watched in a dark room, curtains closed, me and my mate both holding back the tag nuts.
I also squeezed out a few maltezers watching the exorcist. I was living in California at the time, was a dark and windy night, wind chimes gently clanging in the breeze. I went to bed with a hammer that night.
I'm working in the ME where it's dry as a nuns nasty - last night the missus and I went to a party at a local compound and had...wait for it...a pint of becks and a few glasses of aussie shiraz. Not posh, but damn...better than the home brew shit I've been drinking for the last 12 months. Best swill ever.
