Man, these are great! I just wasted a huge amount of time reading all of these posts for the first time. I have to say that I love the "I didn't use Frontpage."...."um...we did." LOL
My favorite personal one came from a client for a snowboard/surfing excursion company. I came up with some really great icons and logo with a nice "cool" grey and white colour scheme.
Client: "Could we make the icons a little more abstract? You know, make them have nothing to do with snowboarding or surfing. And maybe have a big helicopter."
Then he showed me a music site that had icon pictures of different planets.
Client: "Like that! You know...abstract!"
Later, the client decided to go ahead with the his site the way it was. But he still wanted the Flash intro. (It had a 522 KB image file on one of the pages!) I worked on the site for a week and a half, with no contract. He was a friend of a friend.
I didn't tell him about the 522 kb file and I said no to the intro.
