"You don't seriously expect me to believe that!" Charlie exclaimed.
"Believe what you like," Matt shrugged, "The facts speak for themselves."
"I was there. You didn't know that Diet Coke would kill that alien. You just panicked and threw it!"
"It's dead, isn't it?"
"It's like those aliens in that crop circle movie."
"Signs? Seriously? One, that was just a film, and two, the liquid isn't what killed this one. Apparently caffeine was toxic to it."
"There's no way you knew that! I didn't know that!"
Matt just shrugged again, his intolerable air of smugness never wavering.
