One of my favs.
Three weeks after the website is done client calls me to his office on a weekend "to discuss the website".
Basically I was a transcriptionist for 16 hours that weekend. While the client was verbally free-forming content for the site.
Mind you I never heard from him again after he recieved my bill.
I found out that later he tried to sue his webhost when he asked them to deliver his "server". As he was moving to another host.
