One of the guys at my previous office did this.
Unfortunately, the message was (and I quote verbatim) "Aren't the IT department shit?"

He had an unfortunate afternoon sweating about getting fired, since he had sent this to everyone: H.R., the CEO, and most powerful of all, the IT department.

Luckily, the IT dept. didn't take his job, they just took the piss for about the next 2 years.
