Eric Decetis is a cartoonist. His name didn't sound familiar. But his cartoons are.
He's the guy who drew those ... uh ... "doggy in the crack" cartoons. I see them in the big bookstores. They're on calendars, shirts, Halloween Costume (Really!), etc.
Here's a TV interview with him, where he talks about his education (a science major), how he gets his ideas, etc.
