Oliver tells his parents that he's so embarrassed by their modest house that he'd rather not have a birthday party at all. Katie decides to teach him a lesson by ambushing him with a surprise party at home with all his wealthy friends.

Katie's least favorite holiday is Valentine's Day, but her desire for a low-key approach is overridden by Greg's over-the-top romantic gestures. Meanwhile Oliver has an expensive gift for the girl he's crushing on, and Taylor tries to put one over on her parents in order to attend a Valentine's Day party.
