Burt Shlubb and Douglas Klump, better known as Fat Man and Little Boy, respectively, are a pair of minor recurring villains in the Sin City series. They appear in That Yellow Bastard, The Babe Wore Red, Family Values and Fat Man and Little Boy, the last of which is a very short story named after the pair. These two low–rent hit men are known for their constant improper use of large, eloquent–sounding words in an attempt to sound smarter than they really are. Their comedy value aside, Shlubb and Klump are genuinely vicious and unrepentant criminals and murderers, but that is the case with all Sin City villains, even these "Comic relief" ones.
