Alex Bailey from Manchester, who recorded the interaction at the Welsh Mountain Zoo, interprets the signs as a direction to free the chimp, The Telegraph reported. One chuckling man taps on the window and copies the chimp’s actions, mimicking the animal’s mimes of opening the window. A bystander can be heard giggling and saying: ‘He wants us to open it’. But the chimpanzee is more focused on trying to make itself understood, as it longingly looks at the people in front of him.
