OMG, I just found the funniest web site.
Despair.com makes a parody of the overbearing motivational Success and Teamwork posters from Successories that are prevalent in the halls of corporate America.
They are called "Demotivators". My favorites are Inspiration, and Discovery. Click the links at the top of each page for more. They will have you rolling with laughter.
And Despair.com has trademarked the term "Dissatisfied customer". When you order, you become one of these illustrious people.
