### Pet Monkey

Guy in a bar playing pool has a pet monkey. Monkey jumps onto the table, grabs the cue ball and stuffs it into his mouth and swallows it. Bartender freaks and starts yelling about how much cue balls cost , etc. The guy tries to calm him down and tells him the monkey will pass it in the next day or so and he'll wash it off real well and bring it back.

Sure enough the guy and the monkey come back into the bar and gave the bartender his cue ball back. Meanwhile the monkey reaches into the peanut bowl, grabs a nut, sticks it in his butt--then eats it. The bartender stares at the monkey who continues to repeat this action again and again. So he asks the guy, "what's up with that?"

"What?"

"your monkey keeps grabbing peanuts one at a time and sticking them in his butt then eating them."

"Oh, that---well, ever since the pool ball incident, he has to measure everything before he eats it."

## Canvass WhiteBorn 8 Sep 1790; died 18 Dec 1834 at age 44. American civil engineer assisted Benjamin Wrightin the construction of the Erie Canal from 1816. To prepare for building the canal, in late 1817, White travelled extensively in Great Britain visiting canals and learning construction methods. With this experience, on his return, he was Wright's principal assistant. Building locks required a hydraulic cement as mortar between the stones. Because of the high cost to import it from England, White investigated making cement from local limestone. He found rock near the canal route in Madison County was very suitable. He obtained a the first U.S. patent for waterproof cement on 1 Feb 1820. White was consulting engineer for many other canal projects, but retired young due to poor health, and died shortly after at age 44.« |
