When Greg's competitive nature becomes destructive, Dharma exposes him to yoga, hoping to lower his stress level. After two classes, however, they both realize Greg's life is out of control when he gets into a macho ""I can do this"" contest with Pete and pulls a groin muscle. Meanwhile, Larry goes to Edward with a scheme to mass-market videos of Dharma's yoga instruction.

When Dharma's charismatic old boyfriend, Leonard, suddenly re-enters her life after a year in India, Greg finds himself extremely uncomfortable around him—especially when it becomes clear that absolutely everyone else, from Greg's parents to even Marlene, absolutely adores Leonard. Weakened by battling a bad cold, Greg is thrown for a loop when Leonard reveals that he has been celibate since he left Dharma and Dharma decides that she and Greg should give abstinence a try as well. Finally, Dharma informs everyone that they should respect Greg's wishes and not see Leonard any more—then everyone simultaneously spots Greg on television enjoying Leonard's company and his benchside basketball tickets.

A gently surreal episode whose humor derives from escalating skewed logic in the Preston Sturges mode: Greg's hostile secretary Marlene (at last the wonderful Yeardley Smith returns!) is offended by her annual staff evaluation as ""Satisfactory,"" while Greg is overjoyed by his ""Superior"" rating until he learns Pete got the same rating. When Greg confronts his boss, he is driven to desperation by the man's apparent complete inability to discriminate between similar items (Tahiti vs. Buffalo as a honeymoon destination, freshly baked bread vs. moldy supermarket bread), and almost unhinged by the boss's decision to put Pete in charge while he is in medical leave. At the same time Greg must deal with Dharma's impulse decision to open a store without first deciding what she will sell, and the fact that the place quickly becomes packed with people who find Dharma's environment strangely soothing and establish a barter economy amongst themselves. There is of course only one ""logical"" conclusion

Greg discovers he should pay more attention to his wife's intuition when Dharma has a nightmare and begs him not to go away on a business trip.

Questioning his place in the universe, Greg begins a journey of self-discovery by exploring his reasons for becoming a lawyer.

Finding that Greg is overwhelmed with paper work (and that her own efforts to help only lead to desktop carnal encounters), Dharma determines to hire him a first-rate legal secretary. She tries to get pointers from Greg's former secretary Marlene, but discovers that Marlene's only real skill is in dodging work. After submitting applicants to a battery of tests, both skill-related and New Age, Dharma finds the perfect secretary: the intelligent, caring, spiritually centered Kim -- who also happens to be a former fashion model. Despite Jane's skepticism, Dharma insists she trusts Greg completely and goes out of her way to throw Kim & Greg together, going so far as to have her accompany Greg to a dance with Kitty and Edward while she goes to a Smothers Brothers vineyard jamboree with Abby and Larry. When the car brakes Kim supposedly had serviced fail, Dharma's trust looks like a fatal mistake...

Dharma & Greg's love life suffers because neither of them can keep from helping other people with their love problems, including Greg's crazy, lovesick secretary Marlene. Their romantic getaway gets postpones so Dharma can set Marlene up with Jane's flaxy ex. Meanwhile, Abby comes up with a scheme to make money and feed Harry at the same time.

In an effort to boost Pete's confidence, Dharma makes the naïve mistake of convincing Greg to leave the practice in Pete's very incapable hands.

After catching Dharma innocently hanging out with her old college tutor---and failed suitor---Charlie, an enraged Greg moves out. Then the misunderstanding turns into a crisis as they both get caught up in the planning of their mutual friends' impending wedding, compelling Greg to seriously reevaluate his own crazy marriage. But when he finally sees the light, it may be too late.

A heart attack scare during Larry's business pitch for his chili causes Edward to reminisce about a simpler time in his life, when he wasn't a high-pressured ""captain of industry"" merely acquiring and merging other companies. Trying to persuade him to adopt an an easier life, Dharma is taken aback when Edward seizes command of a mall sports shoe outlet owned by his company and happily settles in as a crackerjack shoe salesman—until Kitty finds out. Meanwhile, picking up papers that need Edward's signature, Greg gets a taste of what life would be like as his father's business successor; and realizes (as Kitty angrily tells Dharma) that the real reason Edward hasn't retired is because he is waiting for Greg to take his place. Dharma sympathizes with Greg about abandoning the practice he has built up over the past year—but since this seems to consist of crabby Marlene mismanaging the office and Pete ""teaching"" three gorgeous young women a ""course"" in sexual harassment, perhaps the transit

Dharma is the inspiration for her nerdy neighbor/admirer's new comic book heroine, the Blonde Tornado, a sexy, crime-fighting superwoman. While Dharma enjoys her newfound stardom, Greg's life whirls out of control after a newspaper photo of a burglary hails her as a real life hero and him as her cowardly sidekick.

When Dharma discovers that her drivers license has expired, Greg demands that she be a little more responsible—which is when Dharma discovers she has lost the priceless family heirloom diamong ring Kitty gave her. She discovers it on the roof, coated with tar; and when she takes it to a jeweler for cleaning, she learns it is, in fact, just a really good fake, leading to a confrontation with Kitty. Meanwhile, Pete turns to Dharma for help in getting Gretchen to go out with him. Her simple, sound advice works... Soon Gretchen is head-over-heels for Pete—and he can't stand it. Also, we see Marlene as a judgmental book clerk, and learn that Greg has finally fired her.

While Kitty prepares to renew her marriage vows, Dharma entertains Marlene's parents.

In the first part of this special one-hour season and series finale, Dharma and Greg find themselves once again trying to make peace between their polar opposite parents when an argument breaks out over whether the couple will vacation with the Finkelsteins or the Montgomerys. Dharma tries to appease both sides by arranging for everyone to spend the weekend at the Montgomerys' mountain chalet, but when the usual bickering and insults kick into high gear, it finally sends Dharma and Greg over the edge. Meanwhile, back at the office, Pete is left in charge of a routine SEC inspection, but when the agent turns out to be beautiful and female, he invents wild stories about inside trading... oh, just fast forward. (Part 1 of 2)
