HOLLYWOOD, Calif. — Move over John Travolta and Olivia Newton-John!

Tony and Eva Longoria Parker are channeling Grease's Danny Zuko and Sandy Olsson in a new video spoof posted on the NBA star's Web site. The couple teamed up for the video as part of challenge to fans to submit their own musical parodies.

"I've decided to play a game with you," says the San Antonio Spurs guard, who notes that Grease is his wife's favorite film. "Now it's your turn!"

Fans have until Jan. 31 to submit their videos. The winner will receive a trip to Texas to watch Parker and the Spurs in action.
