Steve lived in Stated Island, ...

Steve lived in Stated Island, NY and worked in Manhattan. He had to take the ferry home every night. One evening, he got sown to the ferry and found there was a wait for the next boat, so Steve decided to stop at a nearby tavern. Before long he was felling no pain. When he got back to the ferry slip, the ferryboat was just eight feet from the dock.
Steve. Afraid of missing this one and being late for dinner, took a running leap and landed right on the deck of the boat. “How did you like that jump, buddy?” said a proud Steve to a deck hand. “It was great,” said the sailor. “But why didn’t you wait? We were just pulling in!”

Iodine discovery announced

In 1813, a new substance - iodine - was announced at the French Institute by Nicolas Clément, in the name of its discoverer, Bernard Courtois. In 1811, Courtois had observed violet crystals with a metallic lustre that condensed from the vapour rising from the mother liquor of seaweed ash being leeched in sulphuric acid at his family's saltpetre business in Dijon. Although he made a preliminary investigation of this substance, he lacked the resources to fully research it. For this he turned to C.B. Desormes and Nicolas Clément. They suspected the substance was similar to chlorine, but confirmation of its nature as an element was made independently by Joseph-Louis Gay-Lussac, who named it iode, and Humphry Davy (1814).[Ref: Clément, N., Découverte d'une Substance Nouvelle dans l'Vareck par M.B. Courtois. Ann. Chim., 88, 304-310, 1813.] [Image: iodine crystals deposited from vapour on a col glass surface.]
