The parody artist and singer, on the second day of his eight-day string of video releases, dropped new album Mandatory Fun today (July 15), and after releasing "Tacky," his "Happy" rendition, yesterday, he's tackling Pharrell again with a version of "Blurred Lines" that's bound to get grammar nazis from all over to stand up and cheer.

"Word Crimes," the new video, doesn't reference Thicke's perhaps poor choice of words on the original. Instead, Weird Al is giving a lesson in grammar.

"Everybody shut up," he announces at the beginning of the video before launching into a bit of a tirade against improper English. "If you can't write in the proper way / If you don't know how to conjugate," he sings, "Maybe you flunked that class / And maybe now you find / That people mock you online."

The video is a lyric video of sorts, but its content sort of lends itself to that setup. "I hate these word crimes!" he declares as the words pop up in dictionaries, mangled tweets and more.
