I could go on about how I dislike alignment in general, but I'll stick to the request instead.
In one of the last games we played, our party was fairly evenly split between neutral and good characters. The neutral characters were far more mercenary than the good guys. The twist (unplanned) were that both of the good aligned characters were rather hedonistic, loving to engage in some hanky-panky with some of the attractive npcs we encountered, or drinking, gambling... the big difference being that the good guys did what they could not to hurt others unduly and help others who needed it.
