Maddie and London's 16th birthday parties are scheduled on the same day, even though London's birthday was 6 months ago. London refuses to change her date out of selfishness and bribes people with gifts if they come to her party. Cody gets Maddie the perfect gift. Zack wants it, but Cody won't give it to him; he instead helps find Zack a suitable gift. Aside from her family, only Zack shows up at Maddie's party while everyone else goes to London's, thus earning a hug. Maddie and London both have a miserable time and in the end, reconcile and merge parties.
