Chris has stated that he was first inspired to draw characters from "The Simpsons" when he was five, around the time the show first went to air. He still caricatures fictional characters such as the cast of "The Simpsons", and signs each of his comments with the qualifier "(Simpsons artist)". He is also known for caricaturing real people currently at the centre of the media's attention at that time, such as Prince William and Kate Middleton at the time of their wedding. He incurred controversy in May 2011 when he posted a caricature of Osama bin Laden.
