Free sex

There was this gas station in "redneck country" trying to increase its sales, so the owner put up a sign saying "Free Sex with Fill-up."

Soon a "redneck" customer pulled in, filled his tank, and then asked for his free sex.

The owner told him to pick a number from (1) to (10), and if he guessed correctly, he would get his free sex.

The buyer then guessed (8) and the proprietor said, "No, you were close. The number was (7). Sorry, no free sex this time but maybe next time".

Some time thereafter, the same man, along with his buddy this time, pulled in again for a fill-up, and again he asked for his free sex.

The proprietor again gave him the same story and asked him to guess the correct number. The man guessed (2) this time, and the proprietor said, "Sorry, it was (3). You were close but no free sex this time".

As they were driving away, the driver said to his buddy, "I think that game is rigged and he doesn't give away free sex".

The buddy replied, "No, it's not rigged -- my wife won twice last week."

First telephone twang

In 1875, Alexander Bell and his assistant Thomas Watson had been working on the "harmonic telegraph". In the transmitter room, Watson had been trying to free a reed that had been too tightly wound to the pole of its electromagnet, when it produced a twang. Bell, who had been working in the receiving room heard the twang. He realized that now his dream of speech transmission must be a possibility, for the complex overtones and timbre of the twang he had just heard had a lot in common with the sound of the human voice. The next day, they continued tinkering on their experiment, anxious to achieve more ambitious results.[Image: diagram of earlier device under test in Winter 1873]
