Dharma finds herself inadvertently trying to compete with a visiting childhood friend. Dharma and September grew up together in a commune, and September has remained loyal to her nonconformist ways, such as preparing a salad with greens that ""were growing in the cracks in the sidewalk"" and singing songs taught her by Nelson Mandela. Feeling guilty over how much her own life has changed, Dharma decides to get back to basics. First, she simplifies her wardrobe; then she wonders what else she and Greg can do without—like maybe electricity, or at least Greg's beloved television (just before the Superbowl). But what worries her most is a suspicion that September may have designs on Larry. And she's right—but they're not what she fears.

When Greg starts to dress and act strangely after driving the used car Dharma recently bought, she worries he's been possessed by the spirit of the car's previous owner, a petty criminal and gambler who met an untimely death. Meanwhile, Edward has Larry set up a security camera at his house to help catch the kid who eggs his house every Halloween, but the ""trick"" is still on him.

Greg proposing to another woman? Dharma bringing another man home to meet the folks? This landmark flashback episode takes place six months prior to the series pilot and shows Dharma and Greg's lives before they met and married on their first date. Share in Kitty's chagrin as Greg breaks up with his debutante fiancée, and join Larry as he watches Dharma leave a great guy who ""refuses to get a job.""

A visit from Kirk, a younger alumnus from Greg's law school, launches an unsuspecting Greg into the middle of a crazy college game with very specific rules developed by ""seriously drunk"" undergraduates. Despite Greg's reluctance to engage in a college prank at this stage in his life, Dharma leaves him no choice when she rallies the gang to help him win back his championship title in a relatively amusing parody of Mission: Impossible. Meanwhile, security guard Larry is disturbed when his supervisor Walter points out that he gets special treatment because his daughter is married to the boss's son. When Larry demands Edward rescind all special treatment, Walter obligingly fires Larry.

A little girl forms an attachment to Dharma and Greg; Kitty is ordered to perform community service.
