You guys ever have the Indian guy that calls telling you he's from Microsoft support and that your computer has a problem and if he doesn't fix it immediately, you'll be disconnected from the Microsoft server?
Usually, I just hang up on these, but every now and then I like to mess with them. One time, a guy actually called me back 3 times telling me I was a fool and that I was about to be disconnected from the internet.
Another time, I acted like a novice and the guy spent a good 15 minutes trying to tell me how to give him access. I then said "I'm not following what you are saying, but what is this Ubuntu thing that's on my computer", to which he promptly hung up.
