Make it a reward, rather than a punishment.
I worked for a sales organization that offered that, if the teams' total sales for a month exceeded 120% of the previous month's total, the Sales VP volunteered to sit in a chair (outside) and let the top performers push pies into his face. (Disclaimer: they were just pie tins with whipped cream in them and he wore large sunglasses)
I still have pictures of the (very messy) results. A totally different kind of motivation that can work.
