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 angry birds. If you want to suggest future Phrases of the Week or guess at this week's, you can do so in comments where you can also ask questions about today's video that will be answered by our team of historians. Thanks for watching Crash Course and as we say in my hometown, don't forget to be awesome.
