Why ARE There so many Songs about Rainbows?

In town today, doing TOWNY things. Yesterday was a Town Day, too. Yesterday I saw the Muppet Movie with some of the Darlings. SHE did not want to go again today, even though we are in Town. She also said that even though we are painting the bedroom, I cannot put up Muppet wallpaper. Not even a sneaky border. SHE said that if I stop singing the Muppet theme song for the rest of the day, I CAN take my Rolph dog puppet Muppet out of my storage box. Life is all about give and take. "It's time to put on make-up....., it's time to light the lights...." She didn't mention writing it in the deal!
