<human>: Give me a shortened version of the text

I am a Teaching Assistant for an into level class at my university. Being a TA, I have no control over what I actually teach.  The classes are designed by the class coordinator who then instructs us how to present the material.  I grade all of their assignments and, therefore, know just how bad their grammar is.  

The assignment this week is incredibly repetitive and doesn't require much (if any) brainpower.  While the students are completing their busywork, I make a spur of the moment decision to play [Weird Al's new video 'Word Crimes'] as a fun way to talk about some of the common grammar mistakes I was seeing.  

Well, as luck would have it, halfway through the video the class coordinator comes in.  She's obviously mad but she isn't quite sure why.  Here was our conversation:

"What is this?"

"A grammar video."

"Well, what's the point?"

"To illustrate common grammar mistakes."

"Well , if you are playing music all of the other classes will be like *They're playing music why can't we?* I would think twice about it next time."

Yes, because we wouldn't want them thinking about their grammar! Oh the horrors!  Anyways, she leaves and a few minutes later I get an email addressed to all of the TA's reminding us that all changes in curriculum, "materials even as minor as grammar videos", need to be approved before hand and shared with all sections of the class since she is responsible for curriculum and equality across the sections of the course.  Well great, she's is blatantly calling me out so I have to respond.  We exchange a few emails back and forth and next thing I know, I am emailing her Weird Al's video to be "evaluated" and to see if it needs to be shared with all sections.  I never hear back from her with an evaluation of the video but the next day, each class' website has had the video posted to it.  I assume she did this so that it doesn't look like she overreacted.  450+ students have now been told to watch Word Crimes in an academic setting.
<bot>: Played Word Crimes for my class in order to have some fun and talk about grammar with my students. My course coordinator found out, got mad, and sent it to everyone in the course so that my class isn't at an advantage.
