Calvin has learned what button to push to make the stereo turntable start spinning. This is particularly jarring when he tuns it on at 4 in the morning to watch it spin and there is an actual record on the turntable and the volume is at 11! Quite disorienting being woken to "Heart of Glass" at top volume! I now secure the stereo arm so he can watch the table spin to his hearts content with zero volume and no wear and tear on the expensive needle!
