According to On The Red Carpet, Joan Rivers staged an impromptu publicity stunt to drum up sales for her new book. The 79-year-old co-host of E!'s Fashion Police was asked to leave a Burbank Costco after using a megaphone to protest the store for banning her book. Rivers' latest book "I Hate Everything ... Starting With Me" was released on June 5 and has received positive reviews.

"Costco should not be like Nazi Germany," shouted Rivers, according to USA Today. "Next thing they'll be burning the Bible." She then added, "Costco, who sells condoms by the pallet, who sells Paula Deen books and -- which is not good for their customers' health -- they decided to ban my book. This is a First Amendment violation."

The store manager called the police, who arrived and escorted the legendary comedian out of the store, but not before she shouted into the megaphone, "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."

Rivers made a memorable appearance on the FX series "Louie" during its second season, and continues to tour the country with her stand-up material. Her jokes range from how many plastic surgeries she's had, to how many men she's slept with to get to the top, to poking fun at her age. Her latest book is an exercise in being a hater, from tearing down political and entertainment figures to tearing herself apart, as well.
