It's probably no coincidence that I watched a lot of Square One as a child and grew up to be a mathematically inclined adult. (If you did not grow up with Square One, you missed out. It was a sketch comedy show for kids about math. There appear to be whole episodes on YouTube, which I will be watching some of at a later date.) I fell into a YouTube hole of Square One musical numbers this afternoon. This is my all-time favorite. Just try listening without starting to sing along.
