An old man was sitting on a bench in the mall when a young man with spiked hair came over and sat down beside him. The boy's hair was bright yellow and green with orange tips, and he had blue makeup around his eyes. The old man kept looking at him. The boy said, "What's the matter, old man, haven't you ever done anything wild in your life?"
The old man answered, "Well yes, actually, I have. I got drunk once and had sex with a parrot. I was just wondering if you were my son."

Elisha Graves Otis

Died 8 Apr 1861 at age 49 (born 3 Aug 1811).American inventor of the automatic safety brake for elevators, which later made high-rise buildings practical. Before this invention, elevators of his time were extremely dangerous. In 1852, he was employed at a New York bed factory. He realized the need for a “safety elevator”to move people and equipment safely to the upper floors of the building. He strikingly demonstrated his solution at the Crystal Palace Exposition in New York in 1854. In front of a large crowd, Otis ascended in his new elevator. He called for the elevator's cable to be cut with an axe, but the elevator platform did not fall. The brake he invented used toothed guiderails in the elevator shaft and a spring-loaded bar that automatically caught in the toothed rail if the elevator car if the cable failed.
