Thanks for watching. I'll see you next week. Crash Course is produced and directed by Stan Muller. Our script supervisor is Danica Johnson. The show is written by my high school history teacher Raoul Meyer and myself, and our graphics team is Thought Bubble. Last week's Phrase of the Week was, Nobody's business but the Turks. If you want to suggest future Phrases of the Week or guests at this week's, you can do so in comments, or you can also ask questions related to today's video that will be answered by our team of historians.
