How Well Do The 'Couples Retreat' Pairs Know Each Other? (After Taking Our Quiz, It Seems, Not Too Well!)

As you may have read yesterday, MTV News had the enviable task of traveling to tropical Bora Bora to interview the stars of the upcoming comedy "Couples Retreat" (out Friday). As interviewer Josh Horowitz notes in the clip below, the true mark of a good couple is knowing stuff about each other (clearly). So how much do Malin Akerman, Vince Vaughn, Jason Bateman, Kristen Bell, Jon Favreau and Kristin Davis know each other? About enough to win a toaster oven on the "Newlywed Game."

Kristen B. is clearly the champ here, not only knowing which iconic series Jason made his acting debut on ("Little House on the Prairie") but scoring two bonus points by remembering that director Peter Billingsley also made an appearance on the drama.

The least knowledgeable of the cast was funnyman Vince, who had no clue what HBO series Malin appeared on, stalling for nearly a minute before being kindly rescued by our interviewer. (The answer, by the way, is "The Comeback.")

Click play on the super funny clip to watch the cast answer even more question about each other, including Jason's dirty, dirty answer to Kristen's question and why Kristin D. and Jon never would have slept together in high school.
