Musician-parodist Weird Al Yankovic is back, and this time he’s telling everybody to shut up—that is, unless you know how to conjugate.

From the man who brought us hit parodies including “Eat It” and “White & Nerdy” comes a new song titled “Word Crimes” which takes aim at the world’s grammar issues. From possessives to contractions to the Oxford comma, Yankovic brings every grammar rule to the table in an almost four-minute video. And between differentiating irony and coincidence to defining what is figurative and literal, he also touches upon blogging and content creation.

Most of us are advanced enough of writers to know that one should never use numbers as letters, as suggested in the song, but there are a couple of points that Yankovic makes related to content marketing that you may not have known:

It Doesn’t Hurt to Have a Full-time Expert On Board

“You really need a full-time proofreader,” Yankovic jokes, adding “You should hire some cunning linguist to help you distinguish what is proper English.” In reality, hiring an expert to oversee writing and content creation is highly encouraged. In fact, research shows that nearly half of companies plan to turn to a content strategy vendor this year if they haven’t already.

Keep Your Blog in Tip-top Shape

“Saw your blog post, it’s really fantastic. That was sarcastic ‘cause you write like a spastic,” go the lyrics. It’s true that a cohesive, well-written blog can not only promote brand awareness but directly correlate with greater revenue generation. Research shows that blogging is the number one method for increasing site traffic; companies that blog at least 15 times per month get five times more traffic than companies that don’t; and on the whole, 77 percent of all Internet users read blogs.

The parody gives us a good communication tip, too:

Keep Business Communications Professional

“I read your email, it’s quite apparent your grammar’s errant,” Yankovic quips. But in all honesty, nothing is worse than seeing an email from a partner, colleague or customer that is ridden with spelling mistakes. This especially goes for the marketer or editor who is tasked with overseeing content creation. What a bad impression that will give.
