One of the worst days of my life was when one of my techs called me as I hopped on a plane...

  Tech: "hey phil, I just broke $bigcustomer's database"
  Phil: "..."
  Tech: "I typed drop database ImportantDB;2"
  Tech: "instead of drop database Importantdb2;"

Even worse because this was lets say.. a very undersized install due to customer cheapness. And all we had for backups (since who wants to PAY for backups?!?!) was a day-old mysqldump off a slave. It took multiple days to re-import all that data. Customer was not pleased.
