Me: if you got a half an hour to change anything in the world, what would you do?
kid: i would invent some kind of shrink ray
kid: then i would shrink all the people and we wouldn't need as much space or food
me: but you'd have to shrink the cows and chickens too, or what would we eat?
kid: nope, chickens stay the same size but then one chicken would feed a whole bunch of people
me: but how do you kill a giant chicken?
