While listening to music and tapping my foot, I contemplated that if I moved too much, the table itself would shake. This prompted me to have the thought, "The Tables are Dancing." I then imagined that mayhaps a woman might be tied under such a table and thus the shaking table was caused by her movement. Perhaps a bondage club where all the tables are bondage enthusiasts and they are moving a bit to the beat (but not enough to spill, of course).
