Rage Comics Teach English
Rage comics have been giving Internet users (mainly on Reddit and 4chan) a way to share humorous stories with each other, all tied together by dozens of common face templates conveying a number of different emotions, from joy, to embarrassment, to, well, rage.
But it was an English teacher-slash-Redditor, Scott Stillar, who saw an opportunity to use these comics to teach English to his Japanese-speaking students. Hilarity ensued, and the comics were so successful they became their own subreddit, called EFL comics. You can read a blog post about the process HERE.
