What is the most EVIL code you have ever seen in a production enterprise environment?
What is the most evil or dangerous code fragment you have ever seen in a production environment at a company?  I've never encountered production code that I would consider to be deliberately malicious and evil, so I'm quite curious to see what others have found.

The most dangerous code I have ever seen was a stored procedure two linked-servers away from our core production database server.  The stored procedure accepted any NVARCHAR(8000) parameter and executed the parameter on the target production server via an double-jump sp_executeSQL command.  That is to say, the sp_executeSQL command executed another sp_executeSQL command in order to jump two linked servers.  Oh, and the linked server account had sysadmin rights on the target production server.
