The great tightrope walker Blondin strung a wire from one side of the Niagara Falls to the other. A crowd gathered to watch him attempt to walk out over the deadly falls. The silent tension turned to cheers as they watched him walk out, turn and come back.
He asked the crowd, “How many believe that I can walk to the other side and back while pushing a wheelbarrow?” To which they shouted, “We believe, we believe!” And, Blondin did in fact walk out and back with a wheelbarrow.
Upon his return, Blondin asked, “Who believes I could push a man in this wheelbarrow while walking out and back on the wire?” Again the crowd responded with enthusiastic affirmation.
“OK,” he asked, “Who would like to get in?” The crowd fell silent.
