White Ink

While we were sitting around at the Twin Arrows Weekender,
The projector happened to be on, so we could see what the guy on the computer was doing.
He started to print something adn one of my staff noticed that on of the indicators for the ink cartridge was white.
He said, "Hey, I think you're running out of ink."
I said, "No, that the White Ink cartridge."
"Oh, I didn't know they made those. That's a good idea."

There was an awkward moment of silence,
before the room burst out laughing.
