The Spark and How to Get It - S6.E4

After his therapist pronounces him fully recovered from his break-up with Alex, Brian plunges back into the dating world. His efforts at the Club Car yield nothing of interest (despite Antonio's assistance with the "Good Cop, Bad Cop" routine), so he follows the advice of others and starts dating casual friend Joan. That elusive "spark" that is missing from their first three dates finally comes to life when Brian breaks up with her, but the "spark" that was there during their dates is now gone.

Meanwhile, Lowell prepares a commencement address for his alma mater and Casey has trouble getting a good haircut.
