Miracle worker...

Two guys and a union worker were fishing on a lake one day, when Jesus walked across the water and joined them in the boat. When the three astonished men had settled down enough to speak, the first guy asked, humbly, "Jesus, I've suffered from back pain ever since I took shrapnel in the Vietnam War...could you help me?"

"Of course, my son," Jesus said, and when he touched the man's back, he felt relief for the first time in years.

The second man, who wore very thick glasses and had a hard time reading and driving, asked if Jesus could do anything about his eyesight.

Jesus smiled, removed the man's glasses and tossed them in the lake. When they hit the water, the man's eyes cleared, and he could see everything distinctly.

When Jesus turned to heal the union worker, the guy put his hands up and cried, defensively, "DON'T TOUCH ME! I'm on long-term disability!"

Elevator

In 1853, Elisha Graves Otis sold his first safety elevator equipment, having started his business earlier in the year to sell the safety elevator system he had invented the year before. His customer was Benjamin Newhouse in New York City who used it for moving freight. Shortly thereafter, in May 1854, at the Crystal Palace in New York City, Otis created public interest with a daring demonstration. He was hoisted high in the air on a platform fitted with his safety feature. When he called for the rope to be cut, the safety device stopped his fall. By 1857, he installed the first department store passenger elevator at E.V. Haughwout & Co. in New York City. In 1889 he applied the electric motor to power elevators.«
