I was inspired after seeing this article on Digg:

Filmwad - Movie news, trailers, galleries and box office! FEATURED: Dead Meat (The Best Worst Death Scenes)

On top of those death scenes (the slow-knifing in Saving Private Ryan, and the curbing in American History X got me,) here's some more I liked...

Lots of deaths in Indiana Jones movies - the under-the-plane fight resulting in the bad guy getting chopped up by the propeller, the heart-removal and dunking in lava from Temple of Doom, the. the fight (with the same actor that got diced by the propellor in Lost Ark) that ended with the bad guy getting pureed by the rock crusher...

Robocop's got a few - the "death" scene of Alex Murphy, which ended with him getting turned into Robocop, the toxic-waste crash, and subsequent splattering-by-car of one of the bad guys.

Yeah, I'm a sick puppy...
