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 theme is Thought Bubble. Last week's Phrase of the Week was Hawaiian pizza. If you want to suggest future Phrases of the Week or guests at this week's, you can do so in comments, where you can also ask questions about today's video that can be answered by our team of historians. By the way, if you want to wear your glove for Crash Course, there's a Mongol shirt, link in the video info. Thanks for watching Crash Course.
