Within a business, there are two (or more) people chosen (preferably someone at administration level) to a dare. You display (within the organization) jars with the person’s name and dare clearly displayed on it. The jar that ends up with the most cash in it after a certain amount of time is the person that has to perform the "dare."
Employees submit "I Dare You" proposals and the most popular – the ones that generate the most contributions in jars – will be carried out.
This would create a battle between the individuals picked for a dare. They would start filling each others jars with money so they would not have to perform a dare.
