"I Think You Might Like It," the latest holiday jingle by John Travolta and Olivia Newton-John, is one of the most baffling things being passed around right now, which features the Grease co-stars line dancing and singing about Christmas in the cheesiest way possible. The song was released last month as part of the duo's charity album in support of their respective philanthropy projects, The Olivia Newton-John Cancer & Wellness Center and the Jett Travolta Foundation.
