Office lottery pools. They're an innocent way for coworkers to bond. A collective dream to lift you out of the daily grind. But they're also potential scenes of Greek tragedy-style betrayal, greed, envy, loss and devastation.

Wilson insists that she bought it separately, and doesn't plan to share the winnings.
