Crash Course is a YouTube channel hosted by the Vlog Brothers Hank and John Green, their attempt to bring Edutainment Show content to web video. The two set off to give comprehensive 'courses' in subjects that they're knowledgeable about, with more staff and professional production than the video blogs that they're primarily known for. Filled with tons of information, constant jokes, funny animations and drawings its a great way to pass the time, but hopefully learn a little, too.
