A husband and wife were in the...

A husband and wife were in the bathroom getting ready for work when the husband looked at his wife and said, "I gotta have you!"
He backed her up against the bathroom door, pulled down her panties and ravaged her. He knew he was doing great because she screamed and wiggled more than she ever had before.
When he finished, he started putting his clothes back on and when he noticed his wife still writhing against the door he said, "That was the best, honey. You've never moved like that before, you didn't hurt yourself did you?"
His wife replies, "No, no. I'll be OK once I can get the doorknob out of my ass."

James B. Eads

Born 23 May 1820; died 8 Mar 1887 at age 66.James Buchanan Eads was an American engineer who built the two-tier triple-arch steel bridge over the Mississippi River at St. Louis, Missouri. At the age of 22, he invented a boat and diving bell which enabled walking on the river bottom. In 12 years' time he made a fortune with his salvage boat operation. During the Civil War, he built ironclad warships. After the war, he built the Mississippi River bridge, the first major bridge to use steel and cantilevered construction, which was opened 4 Jul 1874. Each roughly 500-ft span rested on piers built on bedrock about 100 feet beneath the river bottom. He created a year-round navigation channel for New Orleans scoured out with a system of jetties harnessing the river's water flow (1879).«
