Shannon Wheeler began cartooning for the University of California, Berkeley student newspaper. Later he created Too Much Coffee Man which has run as a weekly newspaper comic, a web comic, in comic books, in magazines and collected in graphic novels. Too Much Coffee Man even lays claim to being the first opera based on a comic book.
The New Yorker began publishing single panel cartoons from Wheeler in 2009. BOOM! published a collection of New Yorker submissions in the book I Thought You Would Be Funnier (2010). Wheeler is currently working on a graphic novel about the Gulf Coast oil spill tentatively titled “Oil and Water.”
