I don\u2019t know if I\u2019ve talked about it here before, but I was a music major in college. I played trombone and wasn\u2019t too bad if I say so myself. But I don\u2019t really do very many music cartoons. I don\u2019t know why, but I don\u2019t seem to. But one day while racking my brain for a new take on the sales graph, it occurred to me that it looked like a vibraphone. But I didn\u2019t think anyone would recognize that, so I tried out marimba, glockenspiel, chimes, and finally settled on the xylophone. Everyone knows the xylophone. I think.
