Imagine this chair is at a table set for a large, fancy dinner. All your friends are there with their spouses. You sit down, the vibrator is turned to its lowest setting–to minimize the noise pollution–and you’re not allowed to stand up or leave before the dinner is over. How long do you think you could keep a straight face? Pay attention to the conversation? Or before someone else at the table made a comment about the buzzing noise coming from your chair?
