A man calls home to his wife a...

A man calls home to his wife and says, "Honey I have been asked to go fishing at a big lake up in Canada with my boss and several of his friends.
We'll be gone for a week. This is a good opportunity for me to get that promotion I've been wanting. Would you please pack me enough clothes for a week and set out my rod and tackle box. We're leaving from the office and I will swing by the house to pick my things up. Oh! Please pack my new blue silk pajamas."
The wife thinks this sounds a little fishy but being a good wife that she is, she does exactly what her husband asked. The following weekend he comes home a little tired but otherwise looking good.
The wife welcomes him home and asks if he caught many fish.
He says, "Yes! Lot's of Walleye, some Bluegill, and a few Pike. But why didn't you pack my new blue silk pajamas like I asked you to do?"
The wife replied, "I did, they were in your tackle box."

Gustave Eiffel

Born 15 Dec 1832; died 28 Dec 1923 at age 91. French civil engineer who specialised in metal structures, known especially for the Eiffel Tower in Paris. He built his first of his iron bridges at Bordeaux (1858) and was among the first engineers to build bridge foundations using compressed-air caissons. His work includes designing the rotatable dome for Nice Observatory on the summit of Mont Gros (1886), and the framework for the Statue of Liberty now in New York Harbour. After building the Eiffel Tower (1887-9), which he used for scientific research on meteorology, aerodynamics and radio telegraphy, he also built the first aerodynamic laboratory at Auteuil, outside Paris, where he pursued his research work without interruption during WW I.«
