Movie scenes you just can't watch

While watching 'Saving Private Ryan' a few days ago, this thread idea popped in my head and it just so happens to coincide with the other movie scene thread.

What movie scenes can you not watch or turn away from when it plays on the screen?

For me, it's in 'Saving Private Ryan' when they are battling the Germans in the town and they blast away the guy walking up the steps in the house. You see the trickle of blood and then another German shoots through the wall and catches the one solider in the neck. The German races through and goes hand-to-hand with the remaining American and yeah...it just gets worse from there.

What about you?

 

Taboo: where Kay Parker watches her son beat off

 

I've watched 'Saving Private Ryan' once. Just once. Because of that very hand-to-hand scene ...

 

Laurence Olivier drilling into Dustin Hoffman's tooth in Marathon Man

 

Is that in the first one? Because she gives Paul plenty of reasons not to do that.

 

Mike calling Nikki over and over in the wee hours of the morning in Swingers.

 

The scene in "Poltergeist" where the researcher's assistant pulls his own face off.

 

How do you know that you can't watch something unless you've watched it? And then if you've watched it, you can't unwatch it.

 

"Dancing with Wolves", when Dunbar is drinking out of the river, then sees the deer head in it. Grosses me out.

 

Casino - head in the vice, eye pops out

 

All of Irreversible, but the rape scene and the beat down of the guy in the bar have to rank in 1 and 1A of hard to watch scenes.

I can't imagine much anything worse than either.

 

The scene from The Tin Drum where a decomposing horse head is used to fish for eels.
