You just got stabbed...

[Cyberjester]

Slowly give a very, very, creepy smile.

I feel it would have the effect needed.

Or this if I felt I could pull if off.

Still, I'm one of those people who doesn't really take pain and/or brokenness into consideration so I'd more than likely just do my level best to throttle the bastard. In a nice way of course
Besides, say something they ignore, jump at them raging whilst coughing up blood. Second one has way more impact and is much more likely to mess with their heads. It isn't a good death unless someone is twitching

I don't die at all.

My dog weighs over a hundred pounds and bites hard enough to break bones.

He also seems to hear every mouse hiccup for five blocks around the house.

If anyone got close enough to my house to be a danger, I've got this eerie feeling I'd wake up the next morning and Moose would be happily wagging his tail with a human femur in his mouth... Bleeding all over my blankets.

Should Moose somehow fail to hear the intruder (unlikely to the point of ludicrous), I imagine it would go something like this *Takes knife from assailant*, *Rams knife into assailants carotid artery*, "Too bad for you, pain helps me focus"

Seriously, it does. The additional adrenaline coursing through my system has helped me chase an entire hunting party (roughly 8) of coyotes across a field more than a mile wide in less than two minutes.
All this across two big-ass dugout mounds, several fences, and then the field.

"Even in death, I forgive you"

Why scar another's life at the end of your's?

"Tell her, won't you mister, that she's still the only one, but a woman's love is wasted when she loves a runnin gun"

 

[Sir Thomas Sean Connery]

may there be a HELL for you! a tartarus, bleak, unending!

...Ok not really (also cookie for the reference)

Sorry Mr. House, Yes Man needs you out of the way.

OT: "So long............. And thanks for all the fish" *dies*

I would start screaming as the person breaks in, continue at a greater volume pre-stabbing, pause momentarily during the stabbing, recommence screaming immediately following the stabbing, and then, as everything goes black, probably break off the screaming.

Assuming I have no time to react. If I see the person breaking in and have time to run, I guess I'd do that, but you didn't let me do that.

 

[Dogstile]

I'd just return the damn favour, talking? Pah!

My friends and I have actually been the victims of knife attacks and we just hit them back. I'm assuming i'd do the same if i actually get stabbed, it's what my friend did.

If my priority suddenly shifted from survival to being witty I'd try to utter something like 'Respawn in 3....2....1....' and hope that my mortality has a cinematic nack for timing.

 

[sora91111]

I say nothing. I flip the guy the bird and die peacefully.

 

[Leonartheinsane]

Probably a one word expletive begining with F being the unsubtle bloke I am.

 

[Zhadramekel]

'Screw you' then spout as many spoilers as I could.

 

[JackKrauserFtw]

i've known my whole life what i would say to my killer. so this is a no brainer.
'Thank you.'

OMIGOSH SO BROODING AND DEEP YOU ARE!

 

[Project_Omega]

"Even in death, I forgive you"

Why scar another's life at the end of your's?

Because it's fun

 

[Project_Omega]

I wouldn't say he is deep as in personality.

Just deep in depression.

And I can see the sarcasm there ;P

 

[monkey jesus]

Hello! my name is Inigo Montoya you killed my father, prepare to die.

 

[cameron196789]

Look at my blood and say "I can not believe it is not butter." leave him with those words.

 

[Laser Priest]

This just about does it.

 

[LordSnakeEyes]

I use his/her physical appearance to utter one last injurious slur, whatever'll get to him personally if I have anything, otherwise there's nothing a swift kick in the sack won't say (for chicks, a grope and my strongest knee to the stomach do I can ruin her ability to make a child.)

Ya, i'm vindictive when it comes to people killing me.

 

[Ledan]

Um.... If i wanted to mentally scar them:
"OH YEAH! That felt sooooo gooood! I think I just orgasmed".... pretty sure that will screw with their minds.
But on a more realistic note:
"NOoooooooooooooooooo..... My one regret is that I didn't survive the release of Skyrim and GW2!" But they wouldn't understand, because I am in Sudan and most people don't speak english.

 

[Lunar Shadow]

Return the favor with the Kabar I have on my desk. That is saying that the fuck didn't get shout after spending time to break down the locked door, as I have a rifle and ammo right next to my desk as well.
