By Denise Martin, Special to The Times "Mean Girls" had us saying "grool!" long after the words were first uttered in the 2004 Tina Fey-penned comedy. The movie, a nicer, more contemporary version of "Heathers," was a surprise hit, making $86 million at the box office and morphing Lindsay Lohan into instant starlet.
