Joan yelled into a bullhorn, "Costco should not be like Nazi Germany. Next thing they'll be burning the bible."
Joan then walked into the store and handcuffed herself to a random woman's shopping cart, where she continued to scream. Costco management called the cops, the footage is hilarious. Even the cops can't help but laugh:

TMZ has video of Joan comparing Costco to Nazi Germany for banning her book "I Hate Everyone Starting With Me." Joan screamed out some things about Costco burning the bible next before she awkwardly handcuffed herself to a woman's cart. If I was that lady, I'd be farting out piss. How dare Joan Rivers take her cart hostage when she's got 18 boxes of frozen pretzels to buy and free samples of delicious corn dogs to eat. But the lady took it well and laughed with Joan until the cops came. Joan later told the local ABC station that Costco is messing with her First Amendment rights.

I love this bitch!
