Weird Al might not be the hero an illiterate Internet wants, but he’s certainly the one it needs.
His newest video, “Word Crimes” (a parody of “Blurred Lines”), is possibly the catchiest grammar lesson created since the days of Schoolhouse Rock. The song and kinetic-type video cover a wide swath of everyday errors, from “its” vs. “it’s” to abusing the word “literally.”

A few of my favorite lines:

“You should never write words using numbers, unless you’re 7 or your name is Prince.”
“Listen up when I tell you this: I hope you never use quotation marks for ’emphasis.'”
“I saw your blog post. It’s really fantastic. That was sarcastic. Cause you write like a spastic.”
He even squeezes in a PG-13 pun with his reference to the aid of “some cunning linguist.” Look at Weird Al, gettin’ scandalous.
