“I don’t know, because most of the graphic novels I’ve heard of and seen reviewed are usually about somebody’s terrible pain, homosexuality or the Holocaust or something like that. But they’re all dark. Are there any funny ones?”- Mort Walker
I've pulled this quote from today's Journalista! site. Mort Walker has a HUGE interview in the new Comics Journal, of which the above paragraph is a mere tiny fraction.
I'm rereading Yotsuba&!, so I think that may qualify as a funny graphic novel, but Mr. Walker's general point is well taken.
