Matthew Diffee makes his living as a cartoonist. But not all of his comics meet the standards of "New Yorker" magazine. So he's collected the best of the rejections from his work and 50 of his cartooning buddies in "The Best of the Rejection Collection: 297 Cartoons That Were Too Dar, Too Weird, Or Too Dirty for The New Yorker." Diffee took time to visit with us on Maine Street to share what it's like to draw cartoons for a living.
