This four-month-old titi monkey (Plecturocebus cupreus) infant stuck his tongue out at the camera! Though it’s easy to assume this behavior was intentional and comedic, due to these monkeys’ close relatedness to us humans, this little one likely was unaware of what humor is. Anthropomorphism, wherein human characteristics are given to animals or objects, is super hard to avoid with animals this cute!
