Looks like Tony and Eva Longoria Parker are ditching Wintry days for “Summer Nights!”

With shiny wigs and cheeky choreography, the Desperate Housewives star and the San Antonio Spur channel Grease’s Danny Zuko and Sandy Olsson in a new video spoof posted on the NBA player’s Web website.

“It’s Eva’s favorite film,” Parker says in video, also posted on his Web site, of the 1978 musical starring John Travolta and Olivia Newton-John.

But fandom isn’t the only reason the two decided to tackle the iconic song and dance. In the video, the basketball star explains that he and his wife have a challenge for their fans.

“I’ve decided to play a game with you,” he says, inviting viewers to submit similar parody videos of musical comedies – in full costume. Says Parker: “Now it’s your turn.”

Longoria Parker and her hubby will watch the entries – which are due on Jan. 31 – and pick a winner whom they’ll fly to San Antonio, Texas, to catch Parker in action with the Spurs.
