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.«

A man wakes up one morning to...

A man wakes up one morning to find a bear on his roof. So he looks in the yellow pages and sure enough, there's an ad for "Bear Removers."
He calls the number, and the bear remover says he'll be over in 30 minutes. The bear remover arrives, and gets out of his van. He's got a ladder, a baseball bat, a shotgun and a mean old pit bull.
"What are you going to do," the homeowner asks?
"I'm going to put this ladder up against the roof, then I'm going to go up there and knock the bear off the roof with this baseball bat. When the bear falls off, the pit bull is trained to grab his testicles and not let go. The bear will then be subdued enough for me to put him in the cage in the back of the van."
He hands the shotgun to the homeowner.
"What's the shotgun for?" asks the homeowner.
"If the bear knocks me off the roof, shoot the dog."
