What TV scene or episode still haunts you?

Most definitely repeatedly watching the plane crash in Lost. Honestly wished I'd never watched that show; that plane crash has definitely made me afraid to fly.

Dang--I'll probably never get it outta my head.

Also, on Breaking Bad when Gus realizes he has been set up and there is an explosive on the wheelchair. He had always been so calm and in control of everything that to see the fear in his eyes in that instant, and then him walking out of the room after, was shocking. 

Grey's where they realize George is the horrifically injured patient they're working on.

WW when Toby finds Josh shot. And then when they tell Donna the news.

WW when POTUS and Abby come off the helicopter and Abby starts moving toward the ambulance where Zoey is then starts running and yells Zoey's name.

The whole WW episode where they deal with Leo/John's death.

That's for starters.

The rapist story on Little House. There's another one but I can't remember what it is. Also super creepy.

Any of the Gillies plots on Murdoch Mysteries (Artful Detective in the States).

(This is probably where I admit I never watched Grey's or ER... so I am not sure about the scenes mentioned)

There was an early ER where Dr Green misdiagnose a pregnant woman who ultimately dies of pre-eclampsia. Bradley Whitford played the husband. My husband watched this after I had just went through pre eclampsia during our first pregnancy. Our situation ended well but the reality hit him like a ton of bricks when he watched. And he told me not to watch.

Wingnut, I had had a friend who died earlier that year under similar circumstances, when that episode came on.  I was a complete mess when it was over with. 

This Little House episode was the first thing that came to my mind when I saw the thread title. The guy wore a clown mask, and that completely solidified my dislike of clowns.

Thanks, Michael Landon.

An oldie-- the movie The Shinning-- where jack N. Says -- here comes Jonny.

Pretty much all of the scenes in ER already mentioned as the one with Carter and Lucy was the first thought that popped in my head when I saw the title of this thread.

I wasn't a regular watcher of ER and I remember that episode, Love Labor's Lost. That whole episode got to me but especially the scene at the end when Dr. Green breaks down on the train ride home.

Others for me are the Home episode of X-Files. Again, the whom episode got me, but especially when the brothers show up at the sherrif's house to kill him and hi wife. They pull up in their car with Johnny Mathis' "Wonderful, Wonderful" playing and then they go in and brutally murder them. The wife is hiding under the bed and watches them kill her dh and then they yank the bed off her and kill her. I can't hear that song now without thinking of that scene.

Another haunting scene for me is the Justice Swerved episode of LA Law. A couple is tried separately, each blaming the other, for the death of their disabled baby. The jury can't decide who did it (or if it was natural causes) so neither is found guilty. In the end scene, in the elevator, you see their fingers quietly touch and you know they murdered that baby together.

The episode "The Body" on Buffy the Vampire Slayer. Seriously.

I could write all day about episodes/scenes that haunt me--just from Joss Whedon shows! 

Funny a lot of us remember scenes from ER. 

One thing that maybe not haunts me so much as it changed how I did things was an ER episode that a child was running around with a metal hanger and fell wherein the hanger got lodged in the roof of the child's mouth endangering his life.

I had a child exactly that age, and I promptly got rid of every single metal hanger in my house and switched to the plastic ones. It was a completely irrational response, but in my defense it was my first kid and I WAS irrational.

Yes.  That one.  That was one of the freakiest episodes EVER.  I read somewhere that it was banned from being shown on network TV in re-runs.  The mother under the bed......

Ugh!

I love Murdoch! We dvr The Artful Detective every week and watch it faithfully!      I really need to delete some of the 90+ episodes I've already watched. That Gillies character was creepy.

I remember gasping in shock the first time I watched the MASH episode about Colonel Blake- so sad.

The most memorable episode ever for me is still the series finale of Newhart- when he wakes up from a dream, next to Suzanne Pleshette. My parents and I watched it faithfully and we were so familiar with the original Bob Newhart Show. We got such a kick out of that final scene!
