Season 4

Emma is upset when she finds out that Karen made Brent an offer he couldn't refuse, while Brent is more than happy and tells everyone in town; Hank doesn't follow through on a promise to Lacey, causing her to turn to Wanda for help, but Wanda takes her new role just a little too seriously; and Davis tries every way he can think of to get Oscar to fix his car, but Oscar's fallen in with an unruly crowd, and no longer respects authority.

Brent is being impersonated by a morning radio show DJ, and feels it necessary to prove to everyone that it's not really him talking. Lacey's new delivery service takes off a little more quickly than she'd hoped, and Karen and Davis find out that "work to rule" actually involves "work".

Oscar and Emma enter the digital world with a new thermometer, but trying to agree on the right temperature raises the heat around their house, and even drags Hank into their argument. Lacey disobeys a road sign and feels Karen's wrath over it; a new security height sticker on the door of Corner Gas gives Brent a new mission in life.

Brent and Lacey are shadowed in their jobs by a couple of high school students, but only teach the kids how ~not~ to do things. Hank is now the proud owner of a fondue pot, which upsets Davis. Emma is also upset by the recent divorce of a friend, and she vows to be nicer to Oscar, upsetting someone else in town.

Hank and Brent begin some demolition work on a local barn, but things take a turn for the worse when Oscar offers his help. Davis, looking for some local fame, hires Wanda to shadow him and capture him "in action". Lacey gives Emma a manicure, but it doesn't take.

Karen tries to raise money for charity and comes up with an interesting way to do it: she locks Davis in a cell until she reaches her goal. Hank, trying to help, keeps Davis company. Brent doesn't like Lacey's idea to give Corner Gas a new look; Wanda insists on fixing Oscar and Emma's toilet, even though she doesn't really know how.

After almost dying, Hank decides to follow his dreams and become a rodeo clown. Karen has to give a speech on eyewitness testimony in front of an audience, and seeks help from Wanda. Oscar is tired of being Emma's bridge partner, so Lacey steps in, not realizing what that entails.

In an effort to get Hank to shut up, Wanda and Brent convince him that the internet is the way to go, so that he can fully express all his thoughts. Things get difficult for Brent when he tries to keep everyone up to date on what's happening in Hank's blog, and finds that 'cheat sheets' are just so last century. Lacey is upset over the success of her friend and the food at The Ruby begins to suffer when Lacey feels that she just can't do anything right. Emma, in an effort to cheer Lacey up, invites Lacey to a BBQ, where a cut-throat game of horseshoes takes place. Wanda tries to help Davis save money on his taxes, but things don't go quite as planned.

Lacey finally gets one-up on Brent when he becomes the outsider after learning that, according to the new Dog River global positioning unit, Corner Gas isn't actually inside Dog River. Hank gets a new job as the town's garbage man, but he's a little too 'into' it for Oscar and Emma's liking. Karen tries to help Davis with the ins and outs of practical joking when she discovers that he just doesn't understand either part of the term.

When both Wanda and Davis sign up for piano lessons with Emma, Wanda's competitive drive kicks into high gear and drives everyone crazy. Oscar is upset about the new air pump at Corner Gas, and he's not the only one... the whole town is up in arms over it. Lacey breaks her arm and learns all about Hank's three stages of injuries; meanwhile, Karen is trying to escape some painful cast-signing memories and so avoids signing Lacey's cast.

Emma takes up sewing and immediately realizes that she needs a quiet place, away from Oscar, where she can sew in peace. She decides to turn Brent's old room into a sewing haven, and Hank helps by taking Brent's old toys out of the way. When Brent finds out, jealousy rears its ugly head. Oscar doesn't like the fact that Emma has him on an allowance and decides to make money on his own by selling cookies. Karen strikes an uneasy bargain with Oscar as his partner, but she has ulterior motives. Davis learns what it's like to be discriminated against when he tries to order food from the Kids' Menu at The Ruby, while Wanda tries to ingratiate herself to both Corner Gas customers and the townsfolk of Dog River by being more 'down home.'

Brent neglects to get Emma a present for Mother's Day, causing her to see red. To make matters worse, Hank shows up with a present, creating a rivalry in Emma's mind. Oscar takes full advantage of the situation when he realizes that he can get away with anything, due to Emma's distraction. Lacey and Davis try to out-embarrass each other, while Karen and Wanda have some trouble putting together their purchase from a Swedish Superstore.

Everyone needs some extra cash: Oscar tries to supplement his income by becoming Dog River's official census taker, but Hank already has that job. Finding that their abilities are equal, Fitzy makes them both census takers, and they come up with some unusual methods for counting the denizens of Dog River. Wanda attempts to sell meal replacement bars, with Brent as her underling, but finds that the profits are being eaten up. Lacey misunderstands a situation, and thinks that Karen and Davis are 'involved' with more than just their jobs.

When Davis buys a classic table hockey game and sets it up at the DRPD, he finds that he's set events in motion that lead to the ultimate showdown... the Summit Series between Karen and Brent. The whole town takes sides in the tournament, and Hank decides that he now wants Karen as his role-model, after watching both her and Brent train. Lacey joins a new club and nominates Emma for some long-overdue recognition.

Karen and Lacey move their friendship up a notch by no longer asking when they borrow things from each other; Oscar, Emma and Wanda decide that Brent needs to expand his horizons, movie-wise, so they prepare to show him his first horror flick; Hank decides that he needs to have the contents of his truck with him at all times, and comes up with a novel solution.

Wanda has a terrible, terrible accident... she breaks Emma's famous Potato Bowl, and has to replace it or suffer Emma's wrath; Hank tries to improve his story-telling skills by mocking Brent and Lacey, while Oscar, Karen and Davis start a new, secret club.

After breaking his glasses and then suffering through endless taunting by Wanda, Brent bites the bullet and tries out laser eye surgery. Hank displays an unusual talent for writing slogans, and Davis and Karen decide to use one on the Dog River Police cruiser, which causes Oscar to take matters into his own hands to remedy the situation.

Things get complicated when Emma forces Oscar and Brent to take Davis along with them on their annual camping trip. Hank's having a first-ever 'good hair day' and tries his best to hold on to more than just the feeling. Lacey and Wanda argue over whose job is more difficult, which leads them to a switch to settle the argument.

Hank has another great idea on how Dog River can increase its tourism, and this one actually works, but has far-reaching consequences. Dog River's sudden fame causes an up-swing in business for both Brent and Lacey, and Wanda finds a new talent that she never knew she had: reporting the news, while Davis takes on some duties as a personal body guard for the movers and shakers of Dog River.
