Dad, What is sex?
An 8-year-old girl asks her father, "Daddy, what is sex?" The father is somewhat surprised that she would ask such a question.
But, he reckons if she's old enough to ask the question, then surely she's old enough for a straight answer.
So, the father proceeds to tell his young daughter all about the "birds and the bees."
After a brief explanation, the little girl appears wide-eyed in disbelief. "By the way, dear, why do you ask?" the father asks.
The little girl replies, "Mommy told me to tell you that dinner would be ready in just a couple of secs."

CorkscrewIn 1860, M L. Byrn of New York City, N.Y., was issued a patent for an improved corkscrew - a “covered gimlet screw with a ‘T’ handle” (No. 27,615). The inventor claimed the design would provide greater strength and durability and which could be manufactured at less cost than prior construction methods using a spiral twist of steel wire that gradually tapered from the handle to the point. Byrn claimed the gimlet-type screw with wider threads would also be strong enough to “remove a bung of the hardest wood from a barel or hogshead.” |
