I learnt that in Community.<p>Jeff Winger:
<i>Conversation was invented by humans to conceal reality. We use it to sweet-talk our way around natural selection, You know who has real conversations? Ants. They talk by vomiting chemicals into each other's mouths. They get right down to brass tracks. Bleh! "Which way's the picnic?" Bleh! "That way." Humans are more evolved. We lie.</i>
