A man walks into a pharmacy and wanders up and down the aisles. The sales girl notices him and asks him if she can help him. He answers that he is looking for a box of tampons for his wife. She directs him down the correct aisle.
A few minutes later, he deposits a huge bag of cottonballs and a ball of string on the counter.
The sales girl says, confused, "Sir, I thought you were looking for some tampons for your wife?"
He answers, "You see, it's like this, yesterday, I sent my wife to the store to get me a carton of cigarettes, and she came back with a tin of tobacco and some rolling papers; cause it's so-o-o much cheaper. So, I figure if I have to roll my own... so does she."

Edison patent

In 1924, Thomas A. Edison was issued a patent for a “Method of Producing Chlorinated Rubber” (U.S. No. 1,495,580), which claimed to be more economical than earlier methods. Natural rubber readily degrades and becomes brittle in the presence of oxygen or ozone in the air. Chlorine is used to replace some hydrogen atoms in the surface molecules of the rubber making it more stable. Edison's method treated very thin rubber strips in a chamber with chlorine gas mixed with the vapour of a highly chlorinated solvent of rubber such as carbon tetrachloride to soften the rubber surface for increased penetration by the gaseous chlorine, followed by other processing. In his patent, Edison envisioned further processing it with naphthaline and fillers, for use as a tough, hard veneer for phonograph records or cylinders.«
