New Yorker cartoons: Editor Bob Mankoff on what's funny

What makes a cartoon funny?

Bob Mankoff, the cartoon editor of the New Yorker, has a better idea than most. He has to pick the best from hundreds of cartoons submitted to the magazine for every edition.

His memoir is named after one of his most memorable lines: How About Never - Is Never Good For You?

He talked to the BBC about how provocative and thought-provoking cartoons need to be "the right amount of wrong".
