Dave discovers a pregnancy test in the trash and suspects Hillary - only to find out that a depressed and out-of-work Vicky has gone off the pill. Completely opposed to having another kid, Dave plays Mr. Fix-It, helping Vicky to pursue job opportunities - with lackluster results. Meanwhile, Larry throws himself into a spelling bee competition, and Mike's lazy streak forces him to buy Hillary's old book reports from the days when she had good grades.

With Vicky and Hillary's menstrual cycles in full swing, Dave must deal with constant mood swings and PMS. After having to take Hillary to the dreaded gynecologist's office, Dave realizes that her doctor is his old friend, who was quite the ladies' man in high school. Needless to say, Dr. Vogel's professional relationship with the family gets personal when Dave doesn't believe Dr. Vogel has changed his player ways. Meanwhile, after Mike calls Larry a nobody, Larry does whatever it takes to gain the respect of his brother.
