My husband just sent me this link and I have been laughing out loud throughout. It is an exchange of emails (with pie charts!) and also a very good and hilarious example of how things can go wrong if you ask people to work for free (also if you have a shoddy business plan).
Please design a logo for me. With pie charts.

Warning, much effing and geoffing.
Enjoy.
