In History of the English Language, we were covering the Great Vowel Shift. My students asked why it occurred, and I had the pleasure of telling them, "No one knows." One of the students spoke up and asked if I had ever seen the Dinosaur Comics about the Great Vowel Shift; when I said I hadn't, she pulled it up on her phone to show me. I laughed so hard when I saw it that I snort laughed in the middle of class. Now that it's nearing the end of the semester and we all need a laugh, I'm sharing the comic with you, too. Enjoy!
