Black and White Cartoon 2012

For many years I have sent a cartoon at Christmas time to my customers. Here is a link to those that have been sent in previous years <[login to view URL]> I work as an IT performance engineer, so each cartoon has a performance related joke or at least tries! For this years cartoon, I want to show the character Bob in a racing car with oval wheels being left behind on the starting line, as the other competitors roar away. The caption will read "Bob wished he has done some pre-race performance testing!" It must be clear that Bob is not moving due to the oval wheels. If you are going to bid please send examples of previous works.
