How to Sell an expensive watch

There was a gentleman walking with two heavy suitcases in an airport terminal.
Someone approached and asked him what time it was. The gentleman bends down to park the two heavy suitcases and stares at his watch. But this was no ordinary watch!
He touches a tiny button and his administrative assistant's face appears.
He asks her, "Mary, what time is it?" Mary answers instantly and with a smile!
The questioner is thoroughly impressed!!!
He asks, "What kind of a watch is that?"
"It's like a TV with two-way real-time communication," the gentleman explains. He adds that the watch is the latest technology with Intel's brand new 128-bit chip with processor speed of 10 Gigahertz.
The onlooker is now quite impressed and wanted to know if he could buy this watch from the gentleman. They agree on a heavy price and the cash was handed immediately. The gentleman takes his watch out and hands it over and then walks away.
The new owner stares at the two heavy suitcases and shouts, "Sir, you forgot your suitcases."
The gentleman stops, smiles, and replies, "No, they are yours now. They are the modems you always need to carry for your new watch.
