Two elderly residents, one male and one female, were sitting alone in the lobby of their nursing home one evening.
The old man looked over and said to the old lady, "I know just what you're wanting, and for $5 I'll have sex with you right over there in that rocking chair."
The old lady looked surprised but didn't say a word.
The old man continued, "For $10 I'll do it with you on that nice soft sofa over there, but for $20 I'll take you back to my room, light some candles, and give you the most romantic evening you've ever had in your life."
The old lady still says nothing but after a couple minutes, starts digging down in her purse. She pulls out a wrinkled $20 bill and holds it up.
"So you want the nice romantic evening in my room," says the old man.
"Get serious", she replies. "I want it four times in the rocking chair!"

Bar codeIn 1974, at 8:01 a.m., a package of Wrigley’s chewing gum with a bar code printed on it passed over a scanner at the Marsh Supermarket, Troy, Ohio, and became the first product ever logged under the new Universal Product Code (UPC) computerized recognition system. Invented by IBM, and approved for use in 1973, the UPC is a 12-number bar code representing the manufacturer's identity and an assigned product number. Within nanoseconds, this information is read with a laser beam moving at around 10,000 inches per second and transfers it to the store’s database computer for price lookup and inventory management. |
