Rubes is a single-panel gag cartoon series created by Leigh Rubin. Many of his cartoons have been collected in a book called The Wild and Twisted World of Rubes, available on his web site. There you can also order his 2013 Rubes desk calender, called Zoo in a Box. And to top it off, with a purchase of the Zoo on the Go app you can receive a daily Rubes cartoon sent right to your mobile phone. There’s a free trial available on the web site too.
