Sunburn

A doctor is making his rounds in the hospital when he comes upon a guy with the worst case of sunburn he has ever seen. The poor guy is burnt raw from head to toe and is in agony. He says to the doctor, "Is there anything you can give me to ease this terrible pain?"
So the doctor says, "Yes, I'll prescribe you some Viagra".
"Viagra?" says the poor guy. "How will that help my sunburn?".
"It won't help your sunburn much" says the doctor, "but at least it'll keep the sheets off it!"

Edison's phonograph

In 1877, Thomas Edison announced his invention of his “talking machine” - the tin-foil cylinder recorder that preceeded the phonograph. He appears to have envisioned it as a business dictation machine. In Sep 1877, he wrote that its purpose was “to record automatically the speech of a very rapid speaker upon paper; from which he reproduces the same Speech immediately or years afterwards preserving the characteristics of the speakers voice so that persons familiar with it would at once recognize it.” The indented tin foil, however, would survive only a few playings. By the first public showing of a phonograph, which took place in New York City in early Feb 1878, its practical applications had not yet been realized.[Image: from Scientific American, 22 Dec 1877]
