“Nonhuman primates don’t just laugh—there’s evidence they can crack their own jokes. Koko, a gorilla in Woodside, Calif., who has learned more than 2,000 words and 1,000 American Sign Language signs, has been known to play with different meanings of the same word. When she was asked, ‘What can you think of that’s hard?’ the gorilla signed, ‘rock’ and ‘work.’ She also once tied her trainer’s shoelaces together and signed, ‘chase.’ Marc Bekoff, University of Colorado, Boulder, professor of evolutionary biology, thinks we’re on the cusp of discovering that many animals have a sense of humor. As Bekoff points out, Darwin argued that the difference between human and animal intelligence is a matter of degree, not of kind.”
