Here is a recording I made sometime between 2000 and 2002. It’s a box that plays an actual tiny vinyl record of laughter. My parents probably bought it in the early 1970s. I remember using the same microphone that I used for recording my stomach noises.  It was connected directly to the microphone input of my Hewlett-Packard Pavilion PC.  While recording the laugh box, it was beginning to malfunction and finally stopped.
