85 Years Old

The old lady was standing at the railing of the cruise ship holding her hat on tight so that it would not blow off in the wind.
A gentleman approached her and said: “Pardon me, madam. I do not intend to be forward, but did you know that your dress is blowing up in this high wind?”
“Yes, I know,” said the lady, “I need both hands to hold onto this hat.” “But, madam, you must know that your privates are exposed!” said the gentleman in earnest.
The woman looked down, then back up at the man and replied, “Sir, anything you see down there is 85 years old. I just bought this hat yesterday!”

Collapsible tube patent

In 1841, the first U.S. patent for collapsible metal tubes was issued to an artist, John Rand (No. 2,252). His purpose was as a "mode of preserving paints, and other fluids, by confining them in close mettalic vessels so constructed as to collapse with slight pressure, and thus force out the paint or fluid confined therein through proper openings for that purpose." The tubes, molded of lead and used to hold oil colours, were provided with caps to keep them airtight. The idea was later reinvented in 1892 for the commercial packaging of tootpaste. The first collapsible polythene tubes were produced in the U.S. for skin-tanning lotion in 1953.
