Grammar, anyone?

I am a grammar nerd.  I admit it.  If I could have gotten away with it, I would have taught grammar all year long to my 10th graders.  My eyes are trained and my ears are ultra sensitive.  Grammar mistakes scream at me everywhere I go.  It's no wonder that this picture, posted on Katie's blog, made me shudder and laugh.  Katie found the picture here, along with a quick apostrophe tutorial.  It's not that difficult, people!!
