Recently a teacher, a garbage ...

Recently a teacher, a garbage collector, and a lawyer wound up together at the Pearly Gates. St. Peter informed them that in order to get into Heaven, they would each have to answer one question. St. Peter addressed the teacher and asked, "What was the name of the ship that crashed into the iceberg? They just made a movie about it."
The teacher answered quickly, "That would be the Titanic." St. Peter let him through the gate. St. Peter turned to the garbage man and, figuring Heaven didn't REALLY need all the odors that this guy would bring with him, decided to make the question a little harder: "How many people died on the ship?"
Fortunately for him, the trash man had just seen the movie and answered, "about 1,500." "That's right! You may enter." St. Peter then turned to the lawyer. "Name them."

Coal mine canaries retired

In 1986, the BBC reported that the British government planned to replace about 200 canaries used in mining pits with modern electronic gas detectors. From 1987, as new technology was gradually phased in, the birds were retired. Live canaries carried in small cages had been used in pits since 1911 to warn of the presence of carbon monoxide, a deadly but colourless, tasteless and odourless gas. John Scott Haldane researched the practice. A small animal with faster metabolism would be more quickly affected by noxious fumes than a human. Canaries were preferred over, say, mice, because they gave an early warning easier to detect. An affected bird would stop chirping, have trouble breathing, sway on its perch and (with trimmed claws) noticeably fall. (Prompt oxygen could be used revive it, for further use.) Or die.«[Image: miner holding up a canary in a cage.]
