A woman places an ad in the local newspaper. “Looking for a man with three qualifications: won’t beat me up, won’t run away from me, and is great in bed.” Two days later her doorbell rings. “Hi, I’m Tim. I have no arms so I won’t beat you, and no legs so I won't run away.” “What makes you think you are great in bed?” the woman retorts. Tim replies, “I rang the doorbell, didn’t I?”

Roller skate

In 1869, Isaac Hodgson received a U.S. patent No. 88,711 for his “roller-skate,” with a padded shoe attached to the skate frame. The earliest known type, using two large wheels on each skate was invented by a Belgian, Joseph Merlin, in 1759. In England, Robert John Tyers, a Picadilly fruiterer, on 22 Apr 1823 patented his Volitos, an “apparatus to be attached to boots ... for the purpose of travelling or pleasure,” which used five small wheels in a single line. Somewhat similar skates with rollers were used to simulate ice skating in a scene of Meyerbeer's opera Prophète, Paris, 16 Apr 1849.* Another American inventor, James L. Plimpton of New York, had a patent for four-wheeled roller skates from 1863, whose right was affirmed at a trial for infringement, 28 Jan 1876.*
