So Bill Gates, Mark Zuckerberg, and Elon Musk are playing golf. [View all]
At some point, Gates stops and pinches his right earlobe. He then starts talking, as though he's speaking to someone who isn't there. After a few minutes, he pinches his earlobe again and tells the others, "It's the latest technology. I had a microphone implanted on my palate, right behind my midline incisors, and a speaker in my ear. The controls have been surgically implanted in my earlobe. It really saves time!"
A couple of holes later, Zuckerberg stops abruptly. His companions see him standing still except for his eyes, which keep looking left and right, even as his head remains immobile. A few minutes later, he relaxes and tells his companions that he's had a projector attached to his cornea that beams digital information straight to his retina. He was getting a text and wanted to read it.
They get to the 18th hole, and Musk walks over to the side of the green, pulls down his pants, and squats. "It's OK," he says. "I'm getting a fax."
