Or, you can send a message to a fellow senior consultant and friend using NET SEND from the command line, which contains a single word, a very rude word that is not fit for these forums. And you don't think what you're doing, and you end up missing a backslash here and a computer name there, and instead of sending it to only his computer, you end up sending it to each and every computer in South Africa's biggest commercial bank's domain. All 36,000 of them.
Yep.
Been there, done that.
Luckily, my project manager at the time was a nice enough guy, and after laughing his arse off, we went rushing up to the bank's IT manager, explaining to him that we were suddenly hit by the new "c*nt" virus, but that we successfully killed it.
Guess what was my nickname in the company afterwards?
Any morals to this story? Sure. If a friend takes you out for too many beers and you end up at work the next morning with a splitting headache and you want to let him know what you think of him by using the one single most offensive word in the english language, text him on his cellphone. Never use NET SEND when hung over. Also, that was back in the day with NT, when it was enabled by default.
But nowadays when the bank irritates me (I still bank with them, though) with either high service fees or ridiculous interest rates, I smile deep inside. Yes, I think to myself: I don't need to get angry. I have already insulted each and every one of this bank's employees, personally. Country-wide. So I guess that makes us even.
