"Damnit, I thought killing those two knuckleheads would be a good thing!" Daria yelled in frustration.
The Old Man gestured with his lollipop, blue this time. "As much as I hate to see life wasted; you would normally be quite correct. Only Beavis and Butt-Head normally stop a bio-terrorism attack. They end up saving the world."
"Total accident?" Daria asked with the tone of someone who already knew the answer.
"Total accident." The Old Man agreed. "After those events occur, they no longer have major positive impact on humans in general."
"And when did this attack occur?"
"It all started the day after you killed them," was the reply.
"You mean I died of the plague, and lost almost six thousand points, because I killed them too damn early!"
"Yes," the Old Man commented, "you're timing could have been a lot better on that one."
Daria muffled her scream of frustration into her arm.
