Take laugh-out-loud humor, mixed with a bit of existential bleakness and modern angst, and you get a taste of Jim Benton's humor. Pretty much every page of Man I Hate Cursive: Cartoons for People and Advanced Bears made me laugh to a greater or lesser degree (usually greater). Some of his themes: love and romance, robots, modern art, family, comic book heroes, and the meaning of life. Plus some other stuff. Let's just say he will take your negative thoughts and make you laugh about them. That may not inspire you to turn your negative outlook around, but laughing is (almost) always a step in the right direction.
(Just a note: in case you know Jim Benton from his many books for children, be forewarned: many of these cartoons are for adults. Not to say there aren't some you can share with your kids, but you may want to be selective, mostly for language.)
