Destroy All Humans!

Greetings earthlings! I, Cryptosporidium 137 of the Furon Empire, happened upon your planet on the way back from destroying the martians. Due to some experiments with atomic weaponry, we lack genitalia and the quality of our clones has degraded. Since you pathetic humans all carry Furon DNA in your genetic code, I have been instructed to collect fresh samples. Survival is not an option, but you should be honoured to support the legacy of the Furon Empire! Destroy All Humans! is a humorous action...
