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.
Nearly speechless, the manager had one last test: "All that's impressive, but can you speak another language?"
The dog replied:"Meow"
