Saving up for 75 years

A small tourist hotel was all abuzz about an afternoon wedding where the groom was 95 and the bride was 23.

The groom looked pretty feeble and the feeling was that the wedding night might kill him, because his bride was a healthy, vivacious young woman.

But lo and behold, the next morning, the bride came down the main staircase slowly, step by step, hanging onto the banister for dear life.

She finally managed to get to the counter of the little shop in the hotel. The clerk looked really concerned, “Whatever happened to you, honey? You look like you’ve been wrestling an alligator!”

The bride groaned, hung on to the counter and managed to speak, “Oh God! When he told me he’d been saving up for 75 years, I thought he meant his money!!”

Michel Chasles

Died 18 Dec 1880 at age 87 (born 15 Nov 1793).French mathematician who, independently of the Swiss-German mathematician Jakob Steiner, elaborated the theory of modern projective geometry, the study of the properties of a geometric line or plane figure that remain unchanged when the figure is projected onto a plane from a point not on either the plane or the figure. In his text Traité de géométrie in 1852 Chasles discusses cross ratio, pencils and involutions, all notions which he introduced. Chasles was the victim of a celebrated fraud paying the equivalent of £20,000 for various letters from famous men of science and others which turned out to be forged.
