Joan Rivers is challenging actress Tilda Swinton to a sleep-off. Swinton has been “performing” at New York’s Museum of Modern Art by occasionally turning up to sleep in a glass box. Rivers says she has turned to the “Jewish Museum in desperation to rival Tilda Swinton,” according to the New York Daily News.

Rivers says, “Her installation is called ‘The Maybe.’ My installation will be called ‘Push Back Time.’ I will sleep in a box as I recover from plastic surgery and people can come and watch as I heal. In the box I will have a plastic surgeon who can read, perhaps a nurse and bandages. I will sleep it off and people can watch as I heal.” No word from the Jewish Museum, but our guess is that they will try to push forward time to avoid becoming an accessory  to Rivers’s Swinton-goading.
