HAHA!!! This reminds me of very first job as a dev. I had to update the employee table to change somebody's name. I ran a very similar update statement without a where clause that was supposed to disable one users account but instead disabled the whole table. To pour salt on the wound they had a trigger on that table that checked to see if the account was disabled and if so, it used some sp_OACreate stuff (sql 7) and disable their AD account. I managed to disable the entire company's AD accounts. Close to 5,000 employees nation wide. It was a bit of a nightmare to say the least that took almost two days for the whole IT staff to unravel.
