It is a little-known fact that all living beings are born with a finite amount of bucks to give. It is little-know due to the fact that most ponies will die long before all of their bucks could been given. But Twilight Sparkle seems to give a buck about everything, and she's depleting her storage far too quickly. This is what happens when Twilight Sparkle runs out of bucks.
