Grammar Lessons

I'm tired of all the "Got XX?" t-shirts, from "Got milk?" to "Got DNA?" to "Got beer?" I'd like to make a shirt that says "Have grammar?" (I do, however, like recent t-shirts I've seen, such as: "Boobies make me smile" and "I heart carbs." )

Also, I am really annoyed by the new cell phone ads with the catch phrase "Where you at?" Don't they know about dangling participles!!
