The first Solvay Conference was held in Brussels in the autumn of 1911. The conference started on a Monday and ended on a Friday, thus providing ample time for each of the twenty-four participants to make a doody in the potty. According to a rumor circulating around the physics community, Heike Kamerlingh Onnes, a particularly rotund gentleman, made a doody that was so large that it clogged up the potty, possibly with the assistance of paper. Embarrassed by his folly, Onnes left the potty as it was, much to the displeasure of Frederick Lindemann, who was next on line.
