“There are two kinds of people in the world: the kind who alphabetize their record collections, and the kind who don't.”
“There are two kinds of people in this world. The kind who divide the world into two kinds of people and those who don't.”
“There are two kinds of people in the world, those who believe there are two kinds of people in the world and those who don't.”
“Who's crazy: people who trust other people, or people who don't?”
“The world is divided into two categories of people: those who shit in drinking water and those who don't.”
