My Pastor told a little of this story this morning and I googled and found the entire account. You might have heard it but it gave me a chuckle...
In 1859 the Great Blondin -- the man who invented the high wire act, announced to the world that he intended to cross Niagara Falls on a tightrope. Five thousand people including the Prince of Wales gathered to watch. Halfway across, Blondin suddenly stopped, steadied himself, backflipped into the air, landed squarely on the rope then continued safely to the other side. During that year, Blondin crossed the Falls again and again -- once blindfolded, once carrying a stove, once in chains, and once on a bicycle. Just as he was about to begin yet another crossing, this time pushing a wheelbarrow, he turned to the crowd and shouted "who believes that I can cross pushing this wheelbarrow." Every hand in the crowd went up. Blondin pointed at one man.
"Do you believe that I can do it?" he asked.
"Yes, I believe you can," said the man.
"Are you certain?" said Blondin
"Yes," said the man.
"Yes, Absolutely certain."
"Thank you" said Blondin, "then sir, get into the wheelbarrow."
