Computer mouse

In 1970, a U.S. patent was issued for the computer mouse - an “X-Y Position Indicator for a Display System” (No. 3541541). The inventor was Doug Engelbart. In the lab, he and his colleagues had called it a “mouse,”after its tail-like cable. The first mouse was a simple hollowed-out wooden block, with a single push button on top. Engelbart had designed this as a tool to select text, move it around, and otherwise manipulate it. It was a key element of his larger project - the NLS (oN Line System), a computer he and some colleagues at the Stanford Research Institute had built. The NLS also allowed two or more users to work on the same document from different workstations. It had been given a public demonstration at a computer conference on 9 Dec 1968.

A True Story

A young man takes the day off work and decides to go out golfing. He is at the second hole when he notices a frog sitting next to the green. He thinks nothing of it and is about to swing when he hears, 'Ribbit. 9- Iron'.
The man looks around and doesn't see anyone. 'Ribbit. 9-Iron.' He looks at the frog and decides to prove the frog wrong. He puts his other club away, and grabs a 9-iron. Boom! he hits it 10 inches from the cup. He is shocked!
He says to the frog, 'Wow that's amazing. You must be a lucky frog, eh?' The frog replies 'Ribbit. Lucky frog.'
The man decides to take the frog with him to the next hole.
'What do you think frog?' the man asks. 'Ribbit. 3-wood.' The guy takes out a 3-wood, and boom! A hole in one. The man is befuddled and doesn't know what to say.
By the end of the day, the man has golfed the best game of golf in his life and asks the frog, 'OK where to next?' The frog replies, 'Ribbit. Las Vegas.'
They go to Las Vegas and the guy says, 'OK frog, now what?' The frog says, 'Ribbit. Roulette.'
Upon approaching the roulette table, the man asks, 'What do you think I should bet?' The frog replies, 'Ribbit. $3000,black 6.' Now, this is a million-to-one shot to win, but after the golf game, the young man figures what the heck. Boom - tons of cash comes sliding back across the table.
The man takes his winnings and buys the best room in the hotel.
He sits the frog down and says, 'Frog, I don't know how to repay you. You've helped me to win all this money and I am forever grateful.'
The frog replies, 'Ribbit, Kiss Me.' He figures, Why not?
After all the frog did for him, it is a small price to pay.
With the kiss, however, the frog turns into a gorgeous 28-year-old young woman.
........... 'And that, sir, is exactly how your wife ended up in my room.'
