NBC has prepared a lengthy preview of "Perfect Couples" which stars Olivia Munn, Hayes MacArthur, and Mary Elizabeth Ellis among others. Over four minutes, the sneak peek begins with how the women in the three couples take up the space in bed and how different the men handle the situation.

Munn and the rest of the cast also gave an insight to the comedy, saying it is so familiar that it feels like a page ripped from Dear Diary. Set to premiere January 20, "Perfect Couples" depicts the misadventures of three engaging couples as they struggle to find out what makes the ideal relationship and how to maintain it through humorous trial-and-error.

The series explores their heroic journey in search of the perfect relationship without destroying each other in the process. Dave and Julia are the relatable, normal couple, but Julia's hope of remaining the cool, low-maintenance chick is tested by Dave's attempts to keep both his wife and his needy best friend Vance equally happy. Vance, along with the neurotic Amy, are the high-passion, high-drama couple who bring out the best and worst in each other.

The third duo features Rex, a reformed party guy, and, and his wife, Leigh, who considers herself as the group's mother hen. Believing that they are relationship experts, Rex and Leigh have attended every class and seminar on relationships - and regard themselves as the "perfect couple."
