Joan Rivers isn’t known for being subtle about things; her standup comedy act is still full of the brash, expletive-laden humor that made her famous, and she’s been more than candid about the many plastic surgeries she’s had over the years. But when she showed up at a Costco in Burbank, California on Tuesday and chained herself to a shopping cart, onlookers were more than a little surprised.

Rivers was apparently irked that the store refused to sell her new book, which she claims is because of a quote by Marie Antoinette.

“You’re banning a book because it says a funny quote by Marie Antoinette? Where is this going to lead us to? 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 to have a funny book to sit on the toilet and read,” Rivers said.

Rivers brought an entourage with her to aid the protest, but was shut down fairly quickly by police. They ended up leaving peaceably, but something tells me this won’t be the last Costco hears of Ms. Rivers.
