It's Always Sunny in Philadelphia has become one of the longest-running and most beloved sitcoms in TV history and for good reason. Its five lead characters, often simply referred to as "The Gang", are far and away from the typically likable and relatable characters seen on other sitcoms; but that's ultimately what makes them so fun to watch. While it's certainly debatable as to which of the five members may be the most or least evil among them, the misdeeds of one in particular have often gone overlooked by fans.
