24 hours
For 24 Hours, you're given the chance to step in and take over a company, the presidency, or something else of your choosing. What do you do with that 24 hours?

Carte blanche for 24 hours? It would be nothing earth-shattering.

Knowing what I know, and knowing whom I despise more than anything, I would take over all of cousin Accorri's pet business ventures and wreck havoc with them. I'd sell all of his most valuable stocks and buy a ridiculous amount of junk bonds with the money. I'd authorise terribly illegal trading ventures in his name and then the next night inform all the regulatory boards of 'his' actions.

Then I'd sell all of his investment properties for pennies on the dollar.

Petty, yes, but it would be very satisfying.
