The lesson in question?
When the Art Department comes looking to Management for some official text on a graphic they're working on, always answer the e-mail promptly.
Otherwise, the Art Department's temporary filler text is destined for the printing press:
BIN LADEN/OSAMA, your plane is now boarding at Gate "Oops."
It goes without saying that the Art Department will undoubtedly catch the axe for this "mistake," no matter whose e-mail neglected to be answered.
