Weird Al Yankovic is on a roll this week with the release of a new video each day to promote his new album, Mandatory Fun .
Following up on Monday's "Tacky," his send up of the Parrell Williams megahit "Happy," today he released "Word Crimes," his parody of Robin Thicke's "Blurred Lines."
Taking online commenters - and the American public in general - to task for improper use of grammar and punctuation, the video is an English teacher's dream.
From the fiercely debated Oxford comma to the misuse of words such as "literally," the video captures Yankovic's obvious frustration with the mangling of English.
Watch the video and weigh in below on your personal grammar pet peeves.
