How would you kill everyone on a planet?

[Not-here-anymore]

I would create a space station that had the ability to destory planets with a giant laser...I would call it the 'Killstar'.

Personally, I'd call it 'A Small Moon', but it's your choice

Oh, and zombie apocalypse ftw! Once I make my zombies immune to fire. And execute everyone called Bill, Louis, Zoey or Francis

 

[Sir_Tor]

Inhabit it with humans, they are bound to screw everyone over sooner or later!

I'll just play Metro Station songs over the entire planet all day everyday. Then just wait for the mass suicides.

 

[Caprice0083]

EMP designed to stop the heart, one blast and cardiac arrest for everyone.

 

[sirkai007]

I would unleash Hillary Clinton.

<--- Or just use this.

 

[DemonicVixen]

Ok just to be extremely random and stupid. I would get someone (not me thanks) to whoo-hoo them to death... Those who know the Sims will know what i am talking about.

 

[chenry]

Gozer.

 

[Mr.Squishy]

With kindness =P

 

[BenOliver21]

make them all infertile and leave them.

 

[BaldursBananaSoap]

ISDE

IMPLOSIVE SUPERSONIC DIARRHEA EPIDEMIC

 

[Crazycat690]

I would have a fat girl sit on their heads until they die^^ then I would put them in a giant blender!!! IM SO EVIL BLAH BLAH BLAAARGH!!!

 

[ioxles]

Like Lobo does it.

Then I'd be unique.

 

[Kazturkey]

Simple, I kill every plant and release a ton of oxygen into the atmosphere.

Then I set the AIR on fire.

Fuck yes.

 

[Russian_Assassin]

With fire.

 

[Virus0015]

I'd do away with them all personally with a small sewing needle, one prick at a time!

 

[Dr.Horrible13]

Invade the planet with an army of Daleks at my command. Nothing can stop me now!

Exactly! But the doctor would come and kill them.
EXTERMINATE! Sonic screwdriver.

 

[Danpascooch]

Make ONE zombie, then sit back, grab popcorn, and watch

(If the first person the first zombie attacks kills it, then THAT PERSON becomes the new "zombie zero")

 

[Nova5]

The hitchhikers guide way!

i.e. Hyper space bypass clearance way!

Also on that note

Spoiler: Here's a picture of the PROPER Arthur Dent (Simon Jones!)

This pretty much tops anything I could have hoped to post, and thus I've changed my mind to this as well. Vogan Demolition Fleet, go!
