An IBM customer had trouble installing software and rang for support. "I put in the first disk, and that was OK. It said to put in the second disk, and I had some problems with it, but I squeezed it in. When it said to put in the third disk - I just can't get it in at all!"

I have family who might do this - but then,I've also family who teaches CAD CAM. - but I don't think they see each other that much!
