A man at the airport realizes he has forgotten his watch. He looks for the time, but can’t find a clock anywhere. He sees another man coming towards him carrying two large suitcases. He goes up and asks, “Do you know the time?”

“Yes,” the other man points to his high-tech looking watch. “Not only does it tell the time, it is a satellite TV, GPS, mini-computer, and MP3 player.”

Astonished, the man, originally looking for the time, now wants the watch. “That is brilliant! I want to buy it, how much are you willing to sell it for?”

“Ah I’m getting sick of this watch anyway. I’ll sell it to you for $900. Here.” He takes off the watch and picks up the two suitcases, “and here are the batteries.”
