The burgulars in the movie Home Alone referred to themselves as the "Wet Bandits" because they always left the water running after they robbed a house.
If Nathan ever turns into a burgular (and how could he, I mean, he's the PERFECT child!!!) his nickname would have to be the Book Bandit. He notoriously pulls books down off every bookshelf in our apartment before leaving a room. It was funny at first, but I'm not sure how many more times Will and I can put the books back before we lose our marbles!!
