Tea set

A girl was given a tea set for her second birthday. It became one of her favorite toys, and when her mother went away for a few weeks to care for her sick aunt, the toddler loved to take her father a little cup of tea, which was just water really, while he was engrossed watching the news on TV. He sipped each "cup of tea" he was brought and lavished generous praise on the taste, leaving the little girl immensely proud.

Eventually the mother returned home and the father couldn't wait to show her how his little princess had been looking after him. On cue, the girl took him his "cup of tea" and he sipped it before praising it to the heavens.

The mother watched him drink it and said: "Did it ever occur to you that the only place she can reach to get water is the toilet?"

Black American patent

In 1875, a U.S. patent was issued for a "Biscuit Cutter" was issued to black American inventor Alexander P. Ashbourne (No. 170,460). The device consisted of a number of metal cutters, which could have various plain or fancy shapes, mounted on a hinged plate attached to a molding board on which dough for cake or biscuits would be rolled out. The plate was then closed over the dough, allowing the cutters to cut through the dough, forming many shapes simultaneously. When the hinged plate was lifted, to simplify removal of the cut shapes, each cutter contained a spring-loaded plate of similar shape to eject the cut dough. Provision was made to store the rolling pin in a concave cross-bar along the back of the hinges.«
