People are just no damn good. ;) From Michael Nesmith's Elephant Parts, apparently.
Due to a computer error that took a century off his age a 105 year old retired teacher in Switzerland was ordered to attend elementary school in 1998. The computer listed only the last two digits of residents birthdates so he and the town's 65 5-year-old's received a letter ordering them to start school. The computer system has since been changed.
