25 years of marriage
After 25 years of marriage, I took a look at my wife one day and said:
"Honey, 25 years ago, we had a cheap apartment, a cheap car, slept on a sofa bed and watched a 10-inch black-and-white TV, but I got to sleep every night with a hot 25-year-old blonde.
Now, we have a nice house, a nice car, a big bed and a big-screen plasma TV, but I'm sleeping with a 50-year-old woman. It seems to me that you're not holding up your side of things."
But my wife is a very reasonable woman.
She told me to go out and find a hot 25-year-old blonde, and she'd make sure that I would once again be living in a cheap apartment, driving a cheap car and sleeping on a sofa bed.

This invention was designed to transmit and receive four independent messages over a single wire, without interference with each other, two in one direction and two in the opposite direction. The separate transmitting keys will transmit a signal with a high or low current strength which are received with sounders that respond only to either the high or low strength signal. |
