IFC compiled a list - unlike everybody else's list this year - regarding scary movies. Sometimes, as you're watching a comedy, science fiction, or drama flick, they pull a fast one on you, and the next thing you know you're jumping out of your seat. For instance, the "Large Marge" scene from Pee Wee's Big Adventure.

"When they finally pulled the driver's body from the twisted, burning wreckage," she groans. "It looked... like THIS!" Suddenly, Nunn's face is replaced by a ghoulish claymation head, which howls at Pee-Wee with bulbous bug eyes, serpentine tongue, and enormous, snaggle-toothed maw. An understandably frightened Pee-wee asks to be let out at the next truck stop, where he learns that he couldn't have gotten a ride from Large Marge; she died in the very accident she described, ten years earlier.

When we got to the Large Marge scene all of us just squealed and laughed our asses off. Then my brothers and sisters insisted that i rewind the scene again. and we did so over and over and over. We must have rewinded that scene at least 40 times before we finally saw thw rest of the movie.
I think that there are a LOT of copies of this movie with a big wear mark on the tape from rewinding this scene.
Surprised the "Boo her!" woman from Princess Bride wasn't on the list, she freaked me out as a kid too. Also, in addition to the "Cornfield" scene in Casino I would add the "Vice" scene which horrified me as an adult. Supposedly happened in real life too.
