New Yorker cartoon editor Bob Mankoff talked about rejection and humor writing in a recent TED talk. Of the 1,000 cartoons the New Yorker gets each week, only 16 or 17 are accepted, Mankoff said.

If you want to see some of the cartoons the New Yorker has rejected over the years, check out Matthew Diffee's book, "The Best of filler list on the Rejection Collection."
