getting users passwords in plain text

Hi Experts,

I have a question that's a bit unethical.

For a company i'm working for i need to find out what the passwords are of oracle users. As changing them means a lot of work for allot of poeple.

Is there anyway i can clear text the password from dba database, i have sysdba and all privs.

any points would be nice also i want to put this into script so if anyone has something ?
