A businessman dragged himself home and barely made it to his chair before he dropped exhausted.
His sympathetic wife was right there with a tall cool drink and a comforting word. "My, you look tired," she said. "You must have had a hard day today. What happened to make you so exhausted?"
"It was terrible," her husband said. "The computer broke down and all of us had to do our own thinking."
A new employee calls the Help Desk to complain that there's something wrong with her password. "The problem is that whenever I type the password, it just shows stars," she says.
"Those asterisks are to protect you," the Help Desk technician explains, "so if someone were standing behind you, they wouldn't be able to read your password."
"Yeah," she says, "but they show up even when there is no one standing behind me."
