Ed and Ted met for the first time in twenty years. "So, how's life been for you?" Ed asked.
"Not too good," Ted replied. "My first wife died of cancer, my second wife turned out to be a lesbian and ran off with another woman and took all our savings, my son's in prison for trying to kill me, my daughter got run over by a bus, my house was hit by a low-flying aircraft, my vintage car rolled off the dockside into the sea, I had to have my dog put down recently, my doctor says that I have an incurable disease and to cap it all my business has just gone bust."
"Oh dear, that sounds terrible." Ed said. "What business were you in?"
"I sell lucky charms," said Ted.

Friction match patent

In 1836, Alonzo Dwight Phillips of Springfield, Massachusetts, received the first U.S. patent for the phosphorous friction safety match (No. 68). The first friction matches, using a mixture of chemicals for their heads, were made and sold in England in 1827. Phillips' match, which could be struck on any rough surface, was the first genuine friction match made in America. Known as “loco focos,” and later as “lucifers,” these matches were made entirely by hand from a mixture of chalk, phosphorus, glue and brimstone (sulphur). The introduction of gas for lighting and cooking, and the spread of cigar smoking, made the lucifer almost a necessity. By the time of the Civil War, about a million matches a day were being manufactured.
