You're dying.

[Irony's Acolyte]

"Always look on the bright side of death"
Then die mid-wistle.

 

[DerpDerpDerp]

>you're friends and family by your side
>you are friends and family

My final words would be: "Rid the world of poor grammar and you will have avenged my death."

 

[Irony's Acolyte]

Oh or I'd use one of my favorite last-words quote:
"Don't let it end like this. Tell them I said something." -Pancho Villa
or
"I do not have to forgive my enemies. I have had them all shot." -Ramon Maria Narvaez

 

[bassdrum]

"Deploying surprise in 5... 4.. 3..."

To be said in a GLaDOS voice. Preferably, pieces will fall out of me immediately after I finish the phrase.

 

[Aenir]

"Do you think there will be...cake?"

 

[The Iconnorclast]

I would either be singing "Always look on the bright side of life" if I died content, but if I was feeling a bit more evil I would say something like "I'll be back" then die with a smile on my face.

Or more likely I would simply say, "I'm not quite dead yet, oh wait, damnit." (Flatline). Me and my family and friends all love Monty Python.

 

[AMX58]

Lord I have sinned but I hope you can see past the "Past"

 

[Broken Orange]

"I should tell you about the treasure chest that I hid. I buried it right next to..."*DEATH*

 

[Vilcus]

"Don't be sad, I'll be back to haunt you."

Edit: Actually I'd say this

"I want to take the ears off, but I can't. I hop, and when I hop, I never get off the ground. It's my curse, my eternal curse! I want to take the ears off but I can't! It's my curse! It's my fucking curse! I want to take the ears off! Please! Take them off! Please!"

 

[KillerH]

"I pray for five minutes in heaven before the devil knows I'm dead"

 

[Romblen]

"I want my casket shot out of a cannon 300 feet away from my plot at the cemetary. The casket should land in the dug out plot, then I want fireworks to shoot off while ACDC's "Thunderstruck" starts playing...Oh, and the murderer was-" *flatlines*

 

[DeathsAmbassador]

"Back in a sec..."

 

[DrButtocks]

"...the game."

You sneaky, sneaky mofo

 

[la-le-lu-li-lo]

"Crab battle..." And here's the reaction...0.o

I extend to you all the love I have for this answer.

OT: In all seriousness, it'd be something meaningful. I'm taking into account I've had time to call my lawyers and make sure the will is updated, if so, yeah, I'll go with something sentimental.

 

[la-le-lu-li-lo]

"I'm tired of this planet and everyone on it."

I like your avatar better than you answer. Is that your Challenger I see there?

 

[Space Cowgirl]

Knowing me and my particular fondness for shouting I'd most likely shout one of the following, hopefully while in the midst of doing something epic:
"Madness? THIS. IS. SPARTAAAAA!" -Dead-
"BEOWUUUUUUUULF!" -Dead-
"I. AM. BEOWU-" -Dead-

Or, if I had no choice in lying in a hospital bed, I'd like to laugh semi-sweetly at first before descending into a insane-driven cackle and descending more into the most evil laugh I can muster. Or just doing the Mandark laugh 'til I die.

 

[Dark Angel Warlord]
