The Pickle

There was a guy on the beach with about 25 gorgeous chicks swarming all around him.
Seeing this, a second guy strolls on up to him and asks, "What's your secret?"
The guy whispers, "All you gotta do is stick a pickle in your pants."
In a fluorish, the second guy runs off and stuffs a pickle in his pants. But when he returns to the shore, he soon discovers that every single girl that looks his way, runs off screaming in bloody terror. Confused, he hurries over to the first guyand desperately asks, "Why are all the girls running away from me?"
The first guy looks up and replies, "The pickle's on the wrong side."

François Hennébique

Born 25 Apr 1842; died 20 Mar 1921 at age 78.French engineer who was an important leader in experimenting with various ways of reinforcing concrete with iron and steel. At the Paris Exposition of 1867, Hennebique saw Joseph Monier's tubs and tanks built of concrete reinforced with wire mesh, and began experimenting with ways to apply this new material to building construction, setting up his own firm (1867). First using reinforced-concrete floor slabs (1879), he progressed to a complete building system, patented 1892, using his invention of a method using hooked connections on reinforcing bars. Hennébique introduced his techniques into Britain when he was commissioned to build a new flour mill in Swansea (completed 1898). This was the first multistorey reinforced concrete building in Britain.
