Only if the "Advertar" fits the context of the game and is killable... for example, lets say I'm playing GTA V in several years time, and the whole advertar thing really kicks off, I'm walking down the in-game street and come across a guy in a gecko suit with a sandwichboard emblazoned: "GEICKO" When he asks for a minute of my time, I want to be able to whip out a knife and stab him in the face.
