1. Talking to a customer who is unable to get her DSL connection to work because she had inserted the network cable in the cd-rom drive.
2. Talking to another customer having the same problem as the one above, but this one has not been able to locate anyplace on his computer where a network cable might fit. When I asked him if he had a network card installed I got the answer (in a very annoyed tone of voice) "Of course I have a network card, do you think I'm an idiot?!? The card is right here in the box from the store."
3. Realizing that this will be a long and very painful day.
