I bought a little metal tambourine at Goodwill for 50 cents that said "What New York needs is a 4 day week". Kooky, but I looked it up and it was given away to those who attended a John Lennon concert he did in New York in the 70's. I looked up a video of the concert and sure enough, people in the crowd are rocking out with the tambourine. Haven't sold it yet, but I'm sure it's at least worth telling the story.
