THERE IS SOMETHING refreshing about talking to another creative person whose work requires the ability to toggle brain function between “editor” and “gag cartoonist.” It is not so easy to shift quickly from judge/jury/red-mark mode — as you dissect someone’s else work — to the “creating from scratch” mode without blowing a mental gasket off the line.

But how Bob Mankoff does it, even I’ll never fully fathom.

Mankoff, of course, is not only a veteran cartoonist, but also the cartoon editor of the New Yorker magazine since 1997. And he shows his gift for deftly riding that professional duality in his new memoir, “How About Never — Is Never Good for You?” — which naturally is a savvy nod to his 1993 cartoon turned catchphrase.

With the new book out, and with Mankoff coming to Washington’s Politics & Prose bookstore next week, Comic Riffs caught up with the editor/cartoonist to talk about how he arrived at his style; how he cultivates a new crop of cartoonists; and the power of an obssessively doting Jewish mother.
