Michael doesn't want to upset the staff so he gets Dwight to pass on news about the company's reduced health provisions. Fed up with his nosiness, Jim and Pam pretend they are suffering from a variety of conditions including Ebola, Mad Cow Disease, spontaneous dentohydroplosion, hotdog fingers, nano-robot infection, inverted penis and anal fissures.
Michael arranges a morale-boosting birthday party for Meredith and is determined to come up with the funniest message in her card. Dwight wants a pact with Jim to fight the downsizing, and Michael regrets showing off when Oscar asks for sponsorship for a charity walk being undertaken by his nephew, who has cerebral palsy.
Just as corporate tells Toby, one of the workers at the Scranton branch, to give a seminar on sexual harassment issues, Michael receives a visit from his obnoxious sales-rep friend Todd Packer. The two chauvinistic friends try to prove that the office is not in need of harassment counseling, but only wind up making the situation worse, causing yet another zany day at the office.
While Michael and Dwight are out of the office for the day trying to close a deal on a new condo for Michael, Jim and Pam arrange for the staff to participate in an "Office Olympics," where the workers play strange, invented games (among them, Dunderball, Hate Ball...and Pam Pong) that they usually play while the boss is out. At the end of the day, the festivities cheer up everyone - even the oblivious Michael.
The Office is forced into the parking lot for the day when a fire starts in the kitchen. To ease everyone's boredom, Jim suggests a game of "Desert Island" and "Who Would You Do?," where certain staff members reveal a little too much information about themselves. Throughout the day, Michael talks business with Ryan, leaving Dwight feeling left out.
While everyone else in the office enjoys the spooky Halloween festivities and talks about the staff's costumes, Michael ponders who he should fire when the threat of downsizing becomes a reality and his boss orders him to fire one of his staff. Meanwhile, Jim and Pam put Dwight's resume on job-searching websites, which may make Michael's job a little easier, and Pam encourages Jim to set his goals higher by applying for a better job, which makes Jim consider his friendship with Pam.
When Dwight embarrasses Michael by punching him in the stomach at work, Jim organizes a lunchtime rematch at Dwight's Dojo.

When Michael and Jan try to nail down a potential new client, Christian, by taking him out to Chili's, Michael surprises everyone with what - or who - he does. Meanwhile, back at the office, Jim finds a semi-autobiographical script that Michael has written called Threat Level: Midnight, and he, Pam, Kevin, and the rest of the Dunder-Mifflin workers have a great time acting it out. Later that night, Pam and Jim share their first unofficial date, complete with dinner (a sandwich), candlelight, and Dwight's pathetic fireworks display.
Michael meets with all of his underlings to discuss their performance in the office so far. However, Michael focuses more on getting feedback about his relationship with Jan than whether or not the workers are doing their job. Later, a nervous Michael plans to shuffle through the employee suggestion box to steal exciting ideas for his imminent discussion with Jan about his own performance, but that falls apart when Jan asks to sit in on the discussion. Meanwhile, Jim and Pam try to keep Dwight under the wrong impression that the day is Friday instead of Thursday.
Michael starts monitoring the emails sent out in the Dunder-Mifflin workplace, upsetting the employees. Meanwhile, Pam believes that the relationship between Dwight and Angela is more than just worker to worker, Jim throws an office BBQ at his house in order to show his roommate the kinds of people he deals with everyday, and Michael, after annoying everyone at his improv classes, crashes Jim's party with a terrible karaoke number.
Michael hosts a Christmas party at the office, but somehow manages to decrease the holiday cheer when he changes the arranged secret Santa pairs to a game of "Yankee Swap," where everyone gives their pre-bought presents to a different, random worker. To boost morale, Michael introduces vodka shots while the others compete for an iPod, Jim hopes that his sentimental present, meant for Pam, doesn't end up with Dwight, and Angela becomes enraged about Michael's party changes.
Michael takes the entire Dunder-Mifflin staff on a motivational cruise aboard a party boat on Lake Wallenpaupack, but his planned presentation is bogged down by numerous distractions, including a dance contest, limbo, snorkel shots, and the pushy Captain Jack.

When Michael burns his foot with his George Foreman mini-grill, he requires the entire office staff to work around his new injury. When the workers aren't so keen on obliging, Michael gets angry and calls in a man in a wheelchair to put out the message that disabled people are people too. Meanwhile, Dwight acts stranger than usual, acting really nice and helpful towards Pam. It isn't until the end of the day when everyone realizes that the car accident Dwight was in earlier that day gave him a concussion (but was overshadowed by Michael's dramatization of his own burn), and Jim and Michael immediately take him to the hospital. Needless to say, Michael doesn't appreciate the extra attention that the doctors and nurses pay Dwight.
When Michael slips some sly references about Pam in his conversations with Jim, Jim quickly tries to do damage control to make sure that no one else in the office finds about his crush on Pam, all while slamming himself with regret for ever telling Michael in the first place. Jim goes to drastic measures, even bonding with Michael at a Hooters restaurant for lunch. Nonetheless, Jim's efforts do little to keep Michael from revealing the secret, but Jim smooths the situation over with Pam to make it seem like nothing more than a tiny crush in the past. Meanwhile, Dwight conducts an investigation about Oscar's mysterious absence from work, and what Dwight finds, though it goes way over his head, is surprising.
When someone soils the carpet in Michael's office, Michael sees it as a form of hatred towards him and realizes for the first time that not everyone may like him.

Meanwhile, Jim realizes why Kelly sits alone in the back of the office as he plays messenger for a childish flirtation between Kelly and Ryan, and Pam tries to cope with the day without Jim to make her laugh.
The Dunder-Mifflin staffers join in kindergarten-like festivities for Valentine's Day while Michael heads to New York City for a conference with the corporate heads. After showing the documenters a tour of his favorite city, Michael accidentally lets slip to the others at the conference that he and Jan hooked up, and he finds himself in hot water when Jan and the new CFO of Dunder-Mifflin hear the story. Back in Scranton, Pam becomes irked when she discovers that Roy hasn't gotten her anything for Valentine's Day, Dwight struggles to find a gift for Angela, and Kelley talks off Jim's ear about her rather desperate affections for Ryan, who is less than interested.
Dwight must confront his fear of public speaking when he is named Dunder-Mifflin's Salesman of the Year. To prepare for a big convention where he is set to give a speech, Dwight turns to Michael to guide him in his quest to conquer the fear. Meanwhile, Pam gets wrapped up with wedding plans, but Jim has plans of a different sort: an escape route out of Dunder-Mifflin and Scranton, at least for long enough so that he doesn't have to witness Pam's wedding. While all of this is happening, the staffers battle it out over control of the thermostat.
