REALITY. So long, meatballs — after six seasons of GTL, grenades and T-shirt time, the self-proclaimed guidos and guidettes who ruled Seaside Heights, N.J. — with minor detours attempting to look legit in South Beach and Italy — are closing the “Shore” house for good. A toast toMTV’s most unlikely celebrity housemates (at least since “The Real World” first bunked seven strangers under one roof) and the engagements, babies and sobriety that they have seen these last three years. But mot importantly, we must give our thanks to the cast for expanding our vocabulary — may you all live long, mint lives in accordance with girl/guy code.
