You see, Lex Luther had taken control of a chemical weapons factory near the stadium. Samp heard about this at halftime, and told the coach he had to run to go "tell Superman." The coach turned around to respond, but Samp was already gone, as if in a flash. Sure enough, about 5 minutes after Samp left, Superman showed up and defeated Lex Luther, allowing the game to go on. After Superman left, Samp came back in time to deliver the greatest halftime speech the team had ever heard. Without Samp around to tell Superman about the danger, who knows what might have happened?
