Geez Louise Skonk! FWIW, I hated high school english.
This might be more correct: "Damn! You're worse than my grade and jr. high schoolteachers."
There was a special on PBS the other night on the American language. They made a point about how it used to be that convential/proper English was preserved in the written word, while different dialects of English/American are spoken regionally around the US, Canada and the rest of the world. They further illustrated how the written word via the internet, email and instant messaging have morphed with all kinds of slang, lack of normal grammer and punctuation. I think they missed an important historical point. With the birth of the telegraph key, there also was developed shorthand with code or slang lacking punctuation in order to shorten the message while still conveying the intent of the sender.
