There were three little boys visiting their grandparents.
The oldest came out and asked his grandpa, "Can you make a sound like a frog, Grandpappy?
Grandpa (being in a kind of ill mood) responds, "No, I don't really want to make the sound of a frog now."
So, the second little boy comes out and asks his grandfather, "Will you please make a sound like a frog?"
Grandpa again says, "No, not now. I don't really want to do that.I'm in a grumpy mood. Maybe later."
Then the third little boy comes out and says, "Grandpa, oh please...Please, please will you make a sound like a frog?"
"Why do all of you boys want me to make a sound like a frog?" Grandpa asked.
The little boy replied with a hopeful face, "Well, Mom said that when you croak we get to go to Disney World!"

### Christian Freiherr von Wolff

Born 24 Jan 1679; died 9 Apr 1754 at age 75.(baron) German philosopher, mathematician, and scientist who worked in many subjects but who is best known as the German spokesman of the Enlightenment, the 18th-century philosophical movement characterized by Rationalism. Wolff's first interest was mathematics. Though he made no original contribution to the discipline, he was important in the teaching of mathematics and instrumental in introducing the new mathematics into German universities. Later, as a philosopher, he developed the most impressive coherent system of his century. Thoroughly eclectic, influenced by Leibniz and Descartes, yet he continued fundamental themes of Aristotle. His system was important in making the discoveries of modern science known in Germany.
