Robert Mankoff stops by the Googleplex for a discussion about whether humor can be modeled. He is the author of the book "The Naked Cartoonist: A New Way to Enhance Your Creativity," published in 2002, about the creative process behind developing magazine-style cartoons. He has also edited dozens of cartoon books and published four of his own. Notably, he edited "The Complete Cartoons of The New Yorker" (Black Dog & Leventhal), the best-selling coffee-table book for the 2004 holiday season, featuring all 68,647 cartoons ever published in The New Yorker since its début, in 1925.
