Raoul also has a Twitter where he tweets Crash Course pop quizzes, as do I. All of those links can be found below. Also, the beloved and I promise not fictitious Stan has agreed to start tweeting, so that's exciting. Thanks for watching and as we say in my hometown, don't forget to be awesome. Oh hey, remember that Mongol shirt from the beginning of the episode? In addition to being a joke, it's a shirt. So many of you requested Mongol shirts that we are giving them to you.
