"Listen," I said. "There was once this legendary French acrobat named Charles Blondin, okay? He was famous in the nineteenth century for doing these impossible daredevil tightrope-walking stunts. He strung a rope across Niagara Falls, a thousand feet long. And this crowd gathered and he walked on the tightrope over the falls, hundreds of feet above the gorge, and the crowd went crazy when he got to the other side, clapping and cheering." Gabe gave me a skeptical glance. "Yeah?" "And then he said to the crowd, 'Do you believe I can do it again?' and the crowd cheered, 'Yes!' And he did it. And the crowd cheered even louder, and he said, 'Do you believe I can do it wearing a blindfold?' And some people in the crowd got scared and shouted, 'No, don't do it,' and others said, 'Yes! You can do it!'" "And he fell," Gabe said. I shook my head. "He did it, and the crowd cheered even louder, and he said, 'Do you believe I can do it on stilts this time?' And the crowd shouted out, "Yes! You can do it!' And he did it, and the crowd roared and got even wilder. So then he said, 'Do you believe I can do it pushing a wheelbarrow along the rope?' And the crowd roared and cheered and said, 'Yes!' And Blondin said, 'You really think I can? You believe it?' And they shouted, 'Yes! Yes, you can!' " Despite himself, despite his teenage cynicism, he was actually listening. For a moment he almost seemed to be a child again, listening to a bedtime story. "Is this true?" "Yes." "He actually did it?" "Yep. He did it. He walked across the tightrope hundreds of feet above the gorge pushing a wheelbarrow, and when he made it to the other side the audience had grown huge and frenzied and totally worked up and they cheered. Really went crazy. So Blondin said, 'Do you believe I can do it again but this time pushing a man in this wheelbarrow?' And the crowd roared and said, 'Yes!' He said, 'You really believe I can do it?' And they all went, 'Yes, definitely! You can do it! We believe in you! Yes! Absolutely!' By that time the crowd was completely behind him. They thought he could do anything. So Blondin said, 'Then who will volunteer to sit in the wheelbarrow?' And the crowd suddenly went quiet. Totally silent. And he said, 'What's the matter? You don't believe in me anymore?' And they were silent for a long time before someone from the crowd finally said, 'Yes, we believe in you. But not that much.' " "Huh. Did anyone ever volunteer to get in the wheelbarrow?" I shrugged. "How'd the guy die?" "In bed. Forty years later. From diabetes."
