A man lay spread out over three seats in the second row of a movie theater.
As he lay there breathing heavily, an usher came over and said, "That's very rude of you, sir, taking up three seats. Didn't you learn any manners! Where did you come from?"
The man looked up helplessly and said, "The balcony!"

Axel Fredrik Cronstedt

Born 23 Dec 1722; died 19 Aug 1765 at age 42. Swedish chemist and metallurgist who was the first to isolate nickel (1751) and notice its slight magnetic properties. A new chemical classification of minerals he made was translated to several languages. Patterns he found in the internal structure of minerals enabled him to distinguish between simple one-compound minerals and those comprised of a mixture of several minerals. He discovered zeolite, a water-softening silicate and analysed the high-density mineral calcium tungstate. By adept use of the blowpipe to intensify a flame and burn a small quantity of a mineral he could make an identification of its chemical composition based on the colouring of the flame. He did not invent the instrument, but founded systematic blowpipe analysis technique.«
