A real italian road sign -indicating the presence of a path for pack or saddle animals- turns into an ironic and irreverent homage to "Family Guy", immortalizing one of the most iconic scenes of the first seasons of the famous cartoon.
 
You will hardly be able to fully appreciate the burlesque vein of this work, unless you have seen the episode in question, where Peter tells his friends that he had to rent a Mustang (which is the name of a Ford sports car but in English it also means "wild horse") and immediately there comes a flashback in which the dumb head of the family stops at the gas station and, after having checked the sides of the horse and having ascertained that there are no flaps to refuel, he is convinced that the petrol pump must be inserted in the rump of the unsuspecting quadruped.
