Seth Godin on fast food marketing (if you can't read the picture, it says "An email offering a free Starbucks iced coffee beverage was distributed by Starbucks partners (employees) with instructions to forward it to their group of friends and family. Unfortunately, it has been redistributed beyond the original intent and modified beyond Starbucks control. Regretfully this email offer will no longer be valid at any Starbucks location effective immediately"). Personally, I'm shocked that people emails would be copied, forwarded, and even modified!
