The Nameless One will take you on in a debate.

Hope you're not a Signer or even a solipsist.

Wrap him in a carpet or something so that he can't move. Place him in a room with nothing interesting in it whatsoever - or, as an alternative, a room with all kinds of nasty things, such as Enter The Matrix, Meet The Spartans, a radio that only plays Lady Gaga, children, George W. Bush, a bullet ant nest and/or a rotting skunk cadaver. Keep him alive as long as you can, watch him go mad and wither. Happy times.

EDIT: Responded to an urgent typo alert.

I would kill him veeeeery slowly, of age.

Mmhmm... in this case I would fetch myself a gun, google Kunovski's place, find and kill him. This time for good.
The drawback of doing that would be that there will be no Kunovski to award the prize... :)

I will have him watch all Twilight Movies without a break together with Justin Bieber.

Nothing is more gruesome I would say!

dear murderers,

I'm sorry to say that I kind of overestimated my resources (and underestimated your creativity! :o) and even though I've read some really great methods in here, I'm really not able to gift a game to everyone who posts a good idea... :(((

I will however come back here from time to time and WILL award the best ways to kill me, so hopefully we'll reach the 1000 ways one day...

my apologies again, I hope you'll come back to this thread to satisfy your "needs" and show me that you care... :)

for now I'm going to grant a 5,99 wish to HereForTheBeer, because his "way" of making profit out of my death really touched me ;) I know I said the killing itself wasn't very original, but the surroundings made me laugh... so, PM me, you freaky monster :D

PS: please, no more "locking in a room forcing to listen/watch/play something" ;o)

Prevent Ubivis from actually killing Kunovski by his method, but obtain the video surveillance of Kunovski's activity with Bieber while being locked in the room, then sell the video on the internet until Kunovski die of shame because people find out he actually liked and had some good intimate time with Bieber in that locked room.

:-D

Drop him in a vat of chocolate.

From my logic textbook:

"Cutting off [Kunovski's] head and then holding his head under water for ten minutes is a sufficient condition for killing him."

I'd inject concentrated hydrochloric acid into his bloodstream - from a 200ml syringe, then fire up a blow torch against all his vital arteries.

Letting him know he'll be the guest speaker at a Tea Party convention in the USA's south wearing a 'Barack Hussein Obama is a devote Christian' t-shirt.
On the way there he'll be eating himself to death on airplane food when he finds out the plastic knife can't cut his wrists.

Shower him with boiling water, then with ice cold, then again with boiling water and so on until his skin comes off.
Then put him in a bath full of salty water.
Then break every bone in his body except for spine, so that he still feels the pain.
Then put him into a meat grinder and make some dog food out of him.

I would get a passing mad doctor to sew his mouth parts to my own anus Human Centepead style, except instead of feeling deeply shamed and evenually commiting suicide, like the Japanese guy at the front in the film, I would frickin go for it - feasting on Mexican food, Vinderloo, chocolate and laxitives, maybe I'd even purpously infect myself with a non-lethal does of Aomebic Disantry.
I'd still hold it in for as long as possable saying useful things like
"There's a storm a brewing in my tummy!"
"The turtle's getting curious!"
and "Better out than in" after every wind breaking
Eventually I would unleash a torrent that would kill the suject either though choking, drowning or sheer toxicity - it would be fascinating to find out which!

I don't want to spoil my hands, so:

Get a huge credit from the mafia by fake signature of Kunovski and give him the money to buy all the GOGs for all of us. Too late he realizes that he needs to pay it back to the mafia and they will slowly cut off every single little part of his body before he dies. Before that happens, they will do the classic: concrete Shoes and a harbour at night :)
