what if the roaches rule the earth? they shall send aireal attacks and goddamned shit on the whole world!!! and the humans put up bugspray but the tiny bastards became immune to the spray. WE ARE DOOMED!!!!
And then they'll eat everything!!! Not just the food, but our houses and our nuclear weapons so then they become giant superbugs and will be big enough to eat a human whole!! (Seriously though, those freaks can eat anything, they got into my fingerpaints once when I was a kid and left multicoloured poo everywhere) :/
