Carol Burnett was appearing on The Garry Moore Show on television at the same time as she was starring in Once Upon a Mattress. This caused some crazy antics. According to Burnett, the double duty meant she got less than an hour of sleep some nights. During one Broadway performance as Winnifred, who cannot sleep on the mattresses with a pea underneath (spoiler!), Burnett actually fell asleep onstage! She came to when she heard the stage manager yelling: “Carol! WAKE UP!”
