Location: Costco, Burbank, CA
Infraction(s): This was definitely was done as a PR stunt, but when the comidienne found out Costco wouldn't be selling her book because of a curse word on the back cover, Joan Rivers conducted a one-woman proteset in a Costco. She handcuffed herself to a shopping cart and ranted over a bullhorn, stating, "This is the beginning of Nazi Germany." She also said, "This is a store that sells 300 rolls of toilet paper at the same time, and I say any customer that buys 300 rolls of toilet paper deserves a funny book to sit on the toilet and read."
