Improved higher resolution version. (Also since this image has been claimed by others, this version has this website on it).
Edit: Some other people may have claimed to drawn this but this is my creation, (February January 2012). Any versions with other web-sites embedded in the image are at best mis-leading.
This is the older version:

apart from the jellyfish or sharks this could also apply to the racing cyclist. replace with potholes and cars maybe.
