If you could make any species of animal extinct, which one would you destroy?

[Cuchulainn]

cats. all of them.

[Aerith's Knight]

All the males in the entire world but for me. My life shall be spent saving the human race, and my nickname shall be "The breeder". Life would be good and I predict death by snoo snoo at 60.

Also, baby seals, but I prefer to do so myself. Makes the sport more interesting.

[Mirage]

How amusing it would be if you just so happened to have a very inheritable and terrible genetic disease :>.

I would make everyone who hate cats go extinct.

[kotora]

them brits

[cloud_doll]

Psychiatrists.

They just don't care D=

[fire_of_avalon]

People who don't like puppies.

[Shoden]

Chavs
French chavs
French chav rabbits
French chav rabbits with a genetic connection to the human race

[Shlup]

All spiders except for daddy long legs.

[The Summoner of Leviathan]

All spiders except for daddy long legs.

But they aren't spiders...

Bedbugs. Those things are gross and insanely hard to get rid of.

[Shlup]

All spiders except for daddy long legs.

But they aren't spiders...

In the US it refers to a spider. Otherwise known as a "cellar spider."

[The Summoner of Leviathan]

:O For me it refers to something else~

[Jiro]

These ones.

[Loony BoB]

Tough call between wasps and mosquitos. I'll probably go with wasps. If we got rid of mosquitos then we'd overpopulate Earth even faster.

[DMKA]

Cockroaches and Texans.

[Madame Adequate]

squids, and

wait for it

Oh, Sarah!

Octopi.

smurf. Those. Things.

Sarah will be along any moment now to relate exactly why I hate octopi so much.

At first I was like "Why on earth would anyone want to get rid of the greatest creatures in the entire universe" but then I realized - it's to preserve our long-term dominance of the planet. I applaud your foresight even as I deplore your desire to kill our Divine friends in the deep.

I would kill all Centipedes. I'm not a fan of spiders either. But of my smurf centipedes are the most horrific thing to walk the earth. If C'thulhu were real he would have the form of a centipede.
