A battle of who got the cheaper gift begins; Lou Ferrigno moves next door.

Doug thinks he has come up with the perfect birthday gift for Carrie: laser eye surgery. That is until Carrie ends up nearly blind from the operation.

Doug stops by Carrie's office, and is introduced to her work-husband Curt. Although Carrie assures him that he has nothing to worry about since Curt is gay, Doug is threatened by just how close the two are. They go to lunch together, share work secrets, and are very tight. He raises his concerns to Carrie, but she tells him that he has the same relationship with Deacon. Doug is not happy with her comparison, and the two than try to make each other jealous by spending more time with their "work spouses" than with each other. Meanwhile, Arthur is jealous of a new dog that Holly has added to her route.

Doug becomes obsessed with his own Super Bowl party after learning that many of his friends will be attending a party thrown by a new co-worker. While Doug is focused on winning back as many guests as possible, Carrie complains that Doug doesn't think about her enough during the day. Problems arise when Doug tries to throw the ultimate Super Bowl party and prove to Carrie he's an attentive husband.

The sixth season opens with a newly svelte Doug and a surprisingly jealous Carrie, who just can't hide her disdain when people constantly compliment her hubby on his weight loss. Doug decides to suprise her by taking her to an old holiday spot of theirs.

During a romantic dinner, Doug is inspired to proclaim his love to Carrie. Carrie is taken by his gesture and suggests that they renew their vows. The two find that planning the wedding is much more troublesome than expected. The ceremony is on again, off again as Doug and Carrie are faced with endless complications, including finding a chimp to serve as Doug's best man. In the midst of the wedding planning Arthur is praying that his wedding present, aged Port wine, will go unused when he discovers the value of the fine wine on E-bay.

Carrie hears that her law firm is laying off people and worries about her job, though her resigning boss is only worried about getting an omelette bar goodbye party. Meanwhile, Doug is in hot water with Deacon when he loses the koosh ball Deacon received from his son as a gift.

When Arthur tries to sell Spence his adjoining burial plot, he somehow winds up selling it to Spence's mother, Veronica. Doug is assigned a new delivery route and is freaked out by a man at one of his daily stops who always answers the door wearing nothing but a towel around his waist. Meanwhile, Carrie takes on dog walking with Holly to make some money after being unemployed for several months, but immediately hates the job and hires a kid to do the walking for her.
