Humour us.
The only case of animal humour that was recorded by scientific journals was a strange case brought in by Jim Anderson, primatologist at Strasbourg university. This scientist was assigned to Koko, a gorrilla that had been innitiated to sign language. One day, a person asked Koko what colour a white towel was, he replied by doing the "red" gesture. The person repeated the question waving the towel infront of the Koko, but the latter kept on telling him that the towel was red. The human didn't understand why the gorrilla was making this mistake and started to lose his patience. Koko reached for the towel and showed the human a little red border on its edge, then proceeded into what the primatologists would call the "game mimic", this means that it lifted its lips, showed its teeth, widened its eyes... could this have been a sign of humour?
:D
im not sure but it makes me laugh thinking about it! silly human!
