Way back when...in the 70s when we were out in Tucson, struggling along, making ends meet, we had an entire wall devoted to copper butterflies, all different sizes and colors. One of our good customers came in all bubbly and declared, "Butterflies are Free!!!". I wan't in a particularly good mood and at the time and said, "Not in this gallery, they aren't." At which point she explained that the quote came from a Broadway play. ...At which point I told her they still weren't free. ...You had to have been there.
