"No, Mr. Scott! You talk into the mouse!"
This actually happened to me about 15 years ago.
My Pointy- Haired Boss (an elderly lady) asked me to replace an employee's dumb ASCII terminal with a shiny new PC and of course, a mouse.
Note that a fellow employee, sitting not more than 4 feet away from the dumb terminal user, had been using her PC AND MOUSE for at least 18 months.
Thus the TWO employees, side by would now have identical equipment. Got it?
Once the new PC was set up, the PHB decided to show the ex-ASCII lady how to log in and use her PC.
When she first picked up the mouse, the ex-ASCII lady waved it at the screen, and disdainfully muttered "So how does thing work anyhow?".
Remember now: her "cow-orker" sitting RIGHT NEXT TO HER had been using an identical PC and mouse for 18+ months!
So I (the only male in the group), - stupidly thinking she had seen the StarTrek movie and was joking, - laughed and replied "No, no, Scotty- you're supposed to talk into it!"
So she held it up to her mouth and seeming puzzled, asked "So what do I say?"
My PHB gave me (now horrified) a nasty look and hissed to me "I'LL handle this! Now go back to your office!"
Anyhow after another 18 months, I found premature retirement - without a golden handshake - and the company went bankrupt. I believe the CEO retired to the Florida Keys...
