Dumb-ass the parody

I'm a big fan of sequential art in any form from cartoon strips to graphic novels - from Calvin & Hobbes to Heavy Metal. I also like adaptations of them (mainly 'cos I don't read many books and I don't think we'll be seeing movie version of, "Where's Wally?" anytime soon). I haven't seen the film but I know there's a foul mouthed school kid in it called, Hit-girl (I live in Essex so these Chavs are two-a-penny). Any such character has got to come from St. Trinians... not so much the recent versions but the old b&w films, which would make you fear for your life if you accidentally found yourself near their school.
