Hiring a new assistant
A business was hiring a new assistant. They put out ads everywhere. A couple of days later, a surprise visitor appeared at their office: a dog, holding a newspaper. The dog pointed to the hiring ad with his paw. The manager, though intrigued, was skeptical and decided to challenge the dog:
" I need a someone who can use a computer."
Without hesitation, the dog hopped onto a desk, powered up the computer, and even printed a document.
Impressed, the manager continued, "Okay, but can you work with spreadsheets?"
The dog promptly opened up Excel, swiftly inputting data and generating graphs.

Spyridon MarinatosDied 1 Oct 1974 at age 72 (born 4 Nov 1901). Spyridon Nikolaou Marinatos was a Greek archaeologist whose most notable discovery was the site of an ancient port city on the island of Thera, in the southern Aegean Sea. The city, the name of which was not discovered, apparently had about 20,000 inhabitants when it was destroyed by the great volcanic eruption of 1500 BC. Among the finds made at the site were the finest frescoes discovered in the Mediterranean region to that time, surpassing even those found at Knossos in Crete. The most famous of these murals is the "Two Boys Boxing" (left).[Image: "Two Boys Boxing" mural, Marinatos's most famous fresco discovery.] |
