At the mall
A blonde decides to try horseback riding even though she has had no lessons or prior experience. She mounts the horse unassisted and the horse immediately springs into motion.
It gallops along at a steady and rhythmic pace, but the blonde begins to slip from the saddle. In terror, she grabs for the horse's mane, but cannot seem to get a firm grip. She tries to throw her arms around the horse's neck, but she slides down the side of the horse anyway. The horse gallops along, seemingly impervious to its slipping rider.
Finally, giving up her frail grip, she leaps away from the horse to try to throw herself to safety.
Unfortunately, her foot has become entangled in the stirrup, and she is now at the mercy of the horse's pounding hooves as her head is struck against the ground over and over. As her head is battered against the ground she is mere moments away from unconsciousness when to her great fortune... the Woolworthâs manager sees her and shuts the horse off.

Remove 2 letters from this sequence (ZPAPERM) to reveal a familiar English word. Otis patentIn 1852, Elisha Graves Otis was issued a U.S. patent for a “Railroad-Car Truck and Brake” (No. 8973). Otis is well-known for his invention of the safety elevator in the same year, which used automatic braking devices to arrest the fall of an elevator car if its supporting cable broke. His inventiveness also spanned making a turbine waterwheel (1848), a steam plow (1857), rotary oven (1858) and steam elevator (1861). In his patent for the railroad car brake, he described a way to link rods running the length of each car in a train that activated brakes, and connected with compensating joints to the next car's rod. Thus a single lever could apply all brakes simultaneously. He also described his idea to construct guards enclosing wheels on the trucks, such that if a wheel or axle broke, the car would safely remain on the tracks.« |
