Grim Adventures Of Billy And Mandy (the) Easter Egg - Darwins powertool award

Actually, Charles Darwin was a naturalist who released the idea of natural selection (the idea that evolution occurs when an animal obtains a trait to help it survive and all animals without that trait die out). The term "Darwin award" is used to describe a person so stupid to perform an action that would kill them. Mandy tells Grim and Billy that "Darwin should pay them royalties" (a royalty being the payment made to the owner of a copyright, patent, trademark or know-how for its use) because Darwin could have based his idea off of them.
