Monkeys
This one is no longer a surprise. You might have already seen a lot of videos involving happy monkeys. They are even fond of making jokes or fun of each other. Some even interact with human beings. They can also be seen laughing. On the wild, they love swinging and leaping through trees. Our closest relatives definitely share our sense of humor. Don’t forget to give them their favorite bananas to make them even happier. It will be worth it once you see that big smile on their face!
