Guerrilla Craigslist Parodies
One of the random gems: "Looking for people who like cake decorating (cupcakes also acceptable). [...] Meet me here promptly at midday Saturday as I have a dentist appointment at 1:45PM."
Implications - The many other typed-out parodies are just as hilarious and could quite possibly have you laughing out loud. This type of graffiti is interesting because it directly involves the viewer, begging them to crack a smile.
