How do I do Mrs.Lovett's hairstyle from the movie Sweeney Todd with Johnny Depp in it? 10 points best answer!?

You know that Pebbles-Flintstone-esque ponytail that all the girls are doing? Where you pile all of your hair on top of your head in a bun? Well, I'd suggest that, but in a psycho way. Instead of a bun, tease the ends, and make it as sloppy as possible. I probably wouldn't brush my hair for a day or two. Just tease it out a lot - and mousse, definitely.
