On a senior citizen bus tour...
On a senior citizen bus tour, the driver was surprised. While the passengers were unloading, to do some sightseeing, one elderly lady stopped and whispered in his ear, "Driver, I believe that I was sexually harassed!"
The driver didn't think much of this complaint, but promised he would check into it soon.
Later, that very same day, as the passengers were unloading again, a second little old lady bent down and whispered in his ear, "Sir, I believe I was sexually harassed!"
This time, he knew it had to be taken care of soon. A few passengers had remained on the bus, and he decided to go back and question them, to see if they had any knowledge of what was going on.
He found one little old man crawling along the bus floor underneath the seats and stooped down to question him. "Excuse me, sir, could I help you?"
The elderly man looked up and said, "Well, sonny, you sure can. I've lost my toupee and I'm trying to find it. I thought I'd located it twice, but they were both parted in the middle, and mine's parted on the side!"

Musical ArcsIn 1900, Nature reported the Musical Arcs invented by William Du Bois Duddell, an English physicist. By means of an arrangement of electric currents he produced a musical note from an arc lamp that could be altered to any pitch is obtained and a tune played. This may be regarded as the first fully electric instrument. While investigating the noise produced by the operation of carbon arc lamps - anything from a low hum to a high-pitched whistle - he found that adding resonance circuits adjusted the pitch of the sounds. His Singing Arc demonstrated this phenomenon using a keyboard connected to an arc lamp, giving audible results without any amplifier. He toured the country with his Singing Arc, as a novelty performance.«* |
