This is a classic Cajun joke...

This is a classic Cajun joke. A pirogue is a shallow flat bottom boat common in Louisiana.

Ol’ Thibodeaux was sitting on his porch one day lookin over da bayou, when he spied ol’ Boudreaux comin by in his pirogue. He said, “Boudreaux, what you got in dat boat wit you?”

Boudreaux said, “I got me some duck tape.”

“Where you going wit dat duck tape?” asked Thibodeaux.

Boudreaux said, “I’m going down to da marsh.”

“What you gonna do with duck tape in da marsh?

“I’m gonna catch me some ducks.”

“Now, hold on, Thibodeaux, you can’t catch with no ducks with no duck tape.”

“Well you watch me.” says Boudreaux, and he goes on by.

A few hours later, Boudreaux comes back from da marsh with a big pile of ducks in his pirogue, and he just waves at Thibodeaux.

Da next day, Boudreaux passes again, and dis time, he’s got a box of nutra-sweet in the pirogue. Thibodeaux says, “Boudreaux, where you going wit dat nutra-sweet?”

Boudreaux says, “I’m going down to da marsh to catch me some nutria rats.”

“Now hold on, Boudreaux.” says Thibodeaux. “You can’t catch Nutria rats with Nutra sweet.”

“Well you watch me.” says Broudreaux, and he goes on his way.

A few hours later, Boudreaux comes back, and he has a big pile of Nutria rats in his bayou. He just waves as he passes Thibodeaux.

The next day, Boudreaux is passing by Thibodreaux again, and Thibodeaux says, “Hey Boudreaux, where you going today?”

Boudreaux says, “I’m going into town.”

“Well what you got in dat boat with you?”

Boudreaux answers, “I got me some pussy willows.”

“Now hold, Boudreaux.” says Thibodeaux. “I’ll get my hat and go wit you.”

First American community water pumping plant

In 1754, the first municipal water pumping plant in America began operation at Bethlehem, Pennsylvania., built by Hans Christopher Christiansen, a Danish millwright. Although the first public water supply in America was installed at Boston, Mass. (1652), it was gravity that moved water piped from springs to a 12 foot square reservoir. The facility at Bethlehem was the first to use a pumping plant, which replaced carriers hauling water up the hill to the village. Water from a spring was piped for 350 feet to a cistern, from which a wooden pump, five inches in diameter, forced it up through bored hemlock logs to a wooden tank in the village square, 70 feet above the pumps. By 1761, operation was expanded to use three iron force pumps driven by an undershot water-wheel. Those pumps were used for 71 years.«[Image: The original frame structure was replaced with a 24-foot-square stone building for the enlarged operations in 1761. It still stands, has been restored, and is now a National Historic Landmark. This entry was previously given as 27 May 1755, based on one source (Kane, Famous First Facts). It has been moved to this page because further research found several books published before 1920 citing this earlier June date.]
