Let me start by saying I’m not a fan of Robin Thicke. But when I heard “Weird Al” Yankovic’s parody of “Blurred Lines” (which, depending on your gender, you may or may not detest), I just couldn’t help but share it. Yes, Thicke’s beat is catchy, but it’s Weird Al’s rant against countless “Word Crimes” (“I could care less” has always driven me nuts, as has the misuse of “its” and “it’s”) that really hooked me.
So for all you fellow grammarians out there … even if you get a little lax every so often … enjoy:

This video is so true but so funny.
A friend shared the video with me on Facebook. As a language Arts teacher, I found it both hilarious and dead on.
