A saxophone player was contracted to do a recording session for a movie. Much to his delight, the soundtrack was pretty much a sax solo from beginning to end.
When the session was over the sax player asked the producer what film his music would be in. The producer admitted that it was an adult film and gave him the name of a theatre that would be showing the premiere.
At the premiere, the Saxophone soloist crept into the movie house, embarrassed, and sat in the back next to an elderly couple who were also trying to be anonymous. The movie was disgusting, ending with a scene involving a dog. The sax player finally had enough, and made his exit past the elderly couple, remarking, "I only came to hear the music."
The old lady replied, "We only came to see our dog!"

Ruth R. BeneritoBorn 12 Jan 1916; died 5 Oct 2013 at age 97.Ruth Rogan Benerito was an American chemist who was a pioneer in the development of wash-and-wear fabrics. Earlier, she investigated fat emulsions and transport of fat in animals. For the Office of the Surgeon General, she developed an intravenous fat emulsion for intravenous feeding to help supply necessary calories for long term patients. Benerito also investigated the reaction epoxies. Her findings have been used not only in the textile industry but also to paper, film, and epoxy plastic manufacturers, and they have been applied in the use of epoxy compounds to preserve wood. Benerito has been granted over 50 patents. Her research has resulted in the development of cotton fabrics that are comfortable, wrinkle-free, stain resistant, “drip-dry” and better able to retard flames. |
