Carlton fans are being urged to put some play in their day this Saturday night for the chance to win great prizes.
Mars is giving away four signed footballs and four $500 cheques ahead of the Round 18 clash with the Kangaroos at Etihad Stadium.
For the chance to win, Blues fans need to be in their seats by 7.00pm then wave and dance with their Carlton scarf.
Those captured on the big screen who are having the most fun will take home the prizes!
