After closing on the sale of a house to Mitch and Cam's friends, Phil and Claire take the two of them out for a celebratory dinner where they proceed to over-indulge in drinks, which leads to some over-sharing, and finally results in waking up the next morning hung over and begging the question - if you'll do anything for family, shouldn't there still be a line drawn somewhere?

Cameron's birthday falls on Leap Day, and with opportunities to celebrate so few and far between, the pressure for Mitchell to get it right is exceptional. Meanwhile, Jay's machismo is in question, and Phil's plans to observe the Leap Day holiday with the boys is thwarted by the girls.
