Word crimes
You know how I love language, so how could I not embrace Weird Al's latest parody? He calls out the "I could care less" crime along with "it's" and "doing good" vs "doing well." Fortunately, he does it all to the catchy blurred lines tune, so it's going to stick in your head.
Plus, if you're NOT all that great at grammar, you may learn a thing or two. (I certainly did!)
This video also makes me think I should learn how to diagram a sentence.
How did I miss that in school?
