Answer
In November 2013, Aron Stevens, better known as Damien Sandow, attempted to cash in his Money in the Bank contract on John Cena but failed, making him the first wrestler to unsuccessfully cash in the contract. This occurred at the Survivor Series pay-per-view event, where Sandow held the Money in the Bank briefcase for over 10 months. Despite the unsuccessful cash-in, Sandow's attempt remains a memorable moment in WWE history.
