Get ready for some smiles! We’re looking at the science of two things that bring us joy: tickles and cuteness. We’ll explain why tickles make us giggle and why you can’t tickle yourself.

Plus, a super cute Mystery Sound and a Moment of Um answering the question: “Can a moon have a moon?”This episode is sponsored by iD Tech (idtech.com/brains).
