"Hi DBA Duncan this developer Dave. We've written this app on the dev system that needs to go live this afternoon. We need system password on live to make it work."

"Do you know who asked for this app to coded? Board member Brian and he's going to be mighty pissed and looking to make heads roll if anyone stands in the way of this app going live!"
