One of the coolest costumes at my school today was a kid who was dressed up as a Leggo. Big cardboard carton with holes cut in it for head and arms and 8 big plastic containers, looked like recycled salad tubs, glued bottoms out like the Leggo peg-thingies, the whole ensemble spray-painted Leggo blue. He looked great and the most expensive thing about it was probably the can(s) of spray paint
