Just found this article. Yet another example of why computers should remain in the domain of people with intelligence rather than the gibbering masses.
A blogger at the New York Times has collected together a few amazing conversations between tech support and insanely thick customers. This is my favourite, where the caller was taking a huge amount of time to follow the tech support agent's instructions:
Agent: Ma'am, I can't help noticing that every time I give you an instruction, it takes a really long time before you get back to me. Is your computer that slow?
Caller: Oh, no, it's just the stupid, stupid design of this computer. Every time I want to click something, I have to unplug the keyboard to plug in the mouse. And then every time I want to use the keyboard again, I have to unplug the mouse. Because there's only one jack.
Agent: Ma'am, you do realize that there's a jack on the keyboard itself? You're supposed to plug the mouse into the keyboard, and the keyboard into the computer.
Caller: Are YOU KIDDING ME!? Oh, wait a minute--yes, I see it now! Oh, holy cow. That's going to be so much easier!
Agent: Just out of curiosity, how long have you been using your computer that way?
Caller: Six weeks!
