Dumping Karen for Pam

Jim and Pam finally getting together was a great moment for The Office since most fans wanted them to find happiness together. However, the start of the relationship came with one huge casualty. Jim abruptly breaks out up with Karen upon realizing Pam is the one.

Despite it working out in the end, it was quite shameless for Jim to just end a long-term relationship at such a whim. The day started with him wanting to get a corporate job and start the next chapter of his life with Karen, but it ends with her dumping her and asking out Pam hours later.

Letting Michael fall into koi pond

The storyline of Michael and Jim becoming co-managers of the Scranton branch provided some fun moments. One of them came when Michael comedically fell into a koi pond during a business meeting and having to explain it to the rest of the office.

Security footage is found and played with Jim getting exposed as going out of his way to not help Michael. The jealousy Jim faces for all the clients not treating him as an equal to Michael creates this low moment for Jim. Michael however does forgive him instantly in awe that Jim could ever be envious of him.

Planning to leave Pam at the dinner party

The Office

The infamous “Dinner Party” episode of The Office is one that almost every fan of the show ranks as an all-time favorite. Jim and Pam get tricked into attending after Michael backs them into a corner making sure they had no backup plans.

A last-ditch effort of claiming his apartment had a fire (later claimed to be a flood) would see Jim state he had to leave. Upon Michael and Jan claiming that Pam could stay, Jim shows no hesitance in wanting to leave her there to escape. Pam however pressures Jim into staying and not abandoning her.

Spending years slacking off at work

THE OFFICE – Jim

Jim endeared us by slacking off at work and never taking it seriously. However, it grew to be a problematic thought as time went on when seeing how hard the rest of the employees worked to continue making a living in an almost outdated business.

Jim eventually does start taking work seriously, but most people would have been fired already for years of going out of your way to avoid doing your job. The lack of care was a shameless perspective for Jim that changed once falling in love with Pam and starting a life together.

Skipping Pam's art show

The tension between Jim and Pam existed in season 3 when they avoided each other at different points following Jim’s confession about his feelings. Pam is the one left heartbroken that she can’t even have a conversation with the person that was her best friend.

Jim does not attend Pam’s first art show exhibit as a way to avoid addressing his feelings for her while dating Karen. It still is a bad look as one of the people that believed in her talent. Pam is crushed at the negative events of the day until Michael is strangely the one that saves the day.

Instigating the fight between Dwight and Michael

“The Fight” is one of the most memorable episodes of The Office that features Dwight and Michael having an actual fight. Michael doesn’t take Dwight seriously when he mentions his karate achievements which eventually causes the tension.

Jim, however, is the one that slyly instigates the fight between the two co-workers. Dwight and Michael once again make fools out of themselves due to Jim’s manipulation. This instance may have seen Jim cross the line since it resulted in actual violence between them.

Revealing that Pam is pregnant when trying to hide it

Jim was often perceived as cool when other characters like Michael struggled in social situations. Pam and Jim worry about Michael revealing the big secret that Pam is pregnant before the wedding to her conservative grandmother.

Everyone is shocked when Jim is the one to accidentally let the big secret out and fails to cover it up. Jim being in the awkward position is quite different and provided some entertainment. Even someone as calm as Jim could turn into a shameless fool when put in the toughest of situations.

Wearing intentionally snarky Halloween costumes

The Office

One of the running jokes each year on The Office was that Jim would find a snarky way to get out of wearing a Halloween costume. Some of the costumes included “Dave” (Jim wearing a name tag that says Dave), three-holed punch Jim (playing black dots on his shirt) and Bookface (writing the world “book” on his face.)

It was a fun bit that made sense given his character, but Jim came off shameful trying to ruin the fun of Halloween for the others that loved dressing up. To his credit, Jim did wear a Popeye the sailor man outfit as part of a family costume with Pam when she’s having a bad day.

Dumping Katy with no chill

The relationship between Jim and Katy is easily forgotten since it lasted for a short time. All the guys in the office tried to win her over when she sold purses in the break room, but Jim was the one to win her over with his sense of humor.

The couple hit it off right away until Jim realized he was just trying to hide his feelings for Pam. Things get ugly on the Booze Cruise when Pam and Roy finally set a date for their wedding. Jim’s broken heart leads to him dating Katy in a brutal manner when ignoring her and saying they should break up when she asks what’s wrong with him.

Buying his childhood home without telling Pam

The most shameless moment for Jim in The Office surprisingly works out in his favor despite being a move most would strongly advise against. Here, Jim makes the bold move of purchasing his childhood house from his parents for him and Pam to move into.

The idea of paying for a home your partner will seemingly spend the rest of her life in is usually something you want to make sure she’s okay with. Pam luckily does like the idea and Jim escapes without getting into too much trouble, but it was clearly a bad move on his part.
