One day, several years ago, I was hanging out in the Math Society lounge when it came up that pretty much everyone used to watch the educational kids show Square One. (It turns out an inordinate number of people in that room also played trombone, but that's another story.) This show was my introduction to a lot of fun math concepts, including Fibonacci numbers, and it was also probably my introduction to Weird Al.
I've had this song about patterns from Square One stuck in my head many a time, starting with the first time I heard it now several decades ago... and now I'm giving this earworm to all of you as today's Wednesday fun video. No no, you don't have to thank me. ;)
