Subtle Changes 3

This contest focuses on things that make you do a double take - the subtle errors in an image that require you to look twice before you can catch them (i.e. paplaukes' image of Escher-like themepost where something isn't quite right with the pillars).

The rules of this game are thus: Take any image and change something about the image in a subtle way. (i.e. a stock ticker with the symbol "l337" floating by or a string of cars in traffic, one of which is driven by a dog). The key in this contest is imagination. As always, quality is a must. We will remove poor entries no matter how much we like you. You'll have 48 hours to submit for this contest so make your submission count.
