Costume idea: "Guy Irritatedly Pulling Headphones Out Of His Ear To Ask 'Sorry, What?' Whenever Somebody Tries To Talk To Him."
Kludge (klooj, n.): a clumsy, inelegant, improvised solution to an engineering problem. Kludge-O-Ween (klooj-oh-ween, n.): a makeshift, half-assed solution to Halloween. When it's too late to worry about finding the perfect costume, it's time to realize that ANYTHING can be a costume.
