The district attorney stared at the jury, unable to believe the "not guilty" verdict he'd just heard. Bitterly, he asked, "What possible excuse could you have for acquitting this man?"
The foreman answered, "Insanity."
The attorney responded, still incredulous, "I could understand that, but... all twelve of you?"

Roller coaster

In 1884, the first gravity-powered American roller coaster that was commercially successful was put in operation at Coney Island, N.Y., the invention of La Marcus Thompson (patent No. 310,966). Passengers rode a train on undulating tracks over a wooden structure 600-ft long. The train started at a height of 50-ft on one end and ran downhill by gravity until its momentum died. Passengers then left the train and attendants pushed the car over a switch to a higher level. The passengers returned to their sideways facing seats and rode back to the original starting point. Admission on the Thompson Switchback Railway was 5 cents and he grossed an average of $600 / day. Within 4 yrs he had built about 50 more across the U.S. and in Europe.
