Do You Know Who Said These Lines on "The Office"?

In one of the show's most beloved pranks, Jim waltzes into the office dressed as Dwight, mumbling another classic line, "Bears. Beets. 'Battlestar Galactica.'" Dwight's comment about identity theft is his exasperated response.

When Michael takes the ladies of the office to the mall in the season three episode "Women's Appreciation," he buys everyone an item from Victoria's Secret. Except for Angela. She's just not having it.

Michael takes the office on a retreat in the season three episode "Beach Games." Because the schedule includes sun-soaking time and a hot dog eating contest, it's Kevin's ideal scenario.

In this season four episode called "Chair Model," Creed explains why he's so anxious for Michael to buy a new ergonomic chair. We never learn the (likely hilarious) reason why it's so important that he have three.

Andy loved to obnoxiously brag about his alma matter, as he does in the season three episode "Gay Witch Hunt." Fun fact: Ed Helms, who plays Andy, was in an a cappella group in real life when he was a student at Oberlin College. The name of the group? The Obertones.

After revealing that she's got a new cat — and showing her furry friend off via a nanny cam she installed in her home and on her computer at work — Angela expresses this frustration in the season five episode "Lecture Circuit Part 2." Folks at the office are later disturbed by what they see because of that camera.

While he became one of the show's most beloved characters (and this quote from season six shows us why), Andy Bernard did not make his first appearance on the show until season three, in the episode "Gay Witch Hunt." He was Jim's coworker at the Stamford branch.

Desperate to save her cat, Bandit, from what she thinks is a fire in the office (thanks, Dwight), Angela throws her cat up to Oscar, who's attempting to escape through the ceiling. Unfortunately, both fall to the floor seconds later.

During the season four episode “Fun Run," Michael believes the office is plagued by a curse because Meredith was hit by a car — which Michael was driving. In addition, Angela's cat Sprinkles died — Dwight euthanized her. Just another day at the office.

Dwight expresses his annoyance for much of the human race in "Phyllis' Wedding" from season three. In the episode, Phyllis marries her boyfriend, Bob Vance, of Vance Refrigeration.

While it's clear that Dwight drove Jim crazy during the years they spent working next to each other at Dunder Mifflin, it's also obvious that Jim delighted in annoying Dwight with his clever office pranks.

Creed imparts this pearl of wisdom in "Fun Run," an episode from season four. It's likely one of the many insights he shares on his blog, www.creedthoughts.gov.www/creedthoughts, which Ryan pretends to set up for him. In reality, it's just a Word doc.

It's not just Stanley who's in an uproar when Jim, temporarily stepping in as boss for Michael, decides to celebrate the birthdays of Creed, Meredith and Oscar with just one party (and one cake), instead of three. This happens in the season four episode "Survivor Man."

Dwight's attempt to teach the office a lesson about fire safety backfires in this season five episode called "Stress Relief." In addition to giving everyone an awful fright, his antics cause Stanley to have a heart attack.

In the season nine episode titled "Suit Warehouse," Meredith is seen wearing a big black wig. This is because, in the previous episode, she was forced to shave her head after everyone assumed she infested the office with head lice. Turns out, the lice came from Pam's daughter.

When Dwight says this in the season one episode "Health Care," Pam asks the obvious follow-up question, "Why would you want to raise your cholesterol?" His response? "So I can lower it."

While Angela makes this statement in "New Guys," which is the first episode of the show's ninth — and final —season, the character's quirky love of cats is obvious from the beginning of the show. True fans can list over a dozen of Angela's cats by name.

Michael poses this question to Rose, a CPR instructor, while (unsuccessfully) attempting to demonstrate how to give mouth-to-mouth resuscitation in the season five episode "Stress Relief." In the same episode, Michael revokes Dwight's responsibilities as safety advisor.

Pam enjoys herself a little too much in the season two episode "The Dundies." As a result, she's banned for life from the restaurant chain. Poor Pam will just have to miss out on their burgers and baby back ribs.

Jim and Pam are tricked into going to Michael's house for dinner in this episode from season five called "Dinner Party." Jim tries to make a break for it by faking a phone call from his landlord telling him his apartment has flooded, but the plot ultimately fails.

Erin shares this belief in the season seven episode "Counseling." The character of Erin, played by Ellie Kemper, does not make her first appearance in the show until the season five episode "The Michael Scott Paper Company."

Oscar makes this comment in the season nine episode "A.A.R.M.," which is the second-to-last episode of the series. He's talking about the unfashionable way he believes Angela dresses her son.

This classic Creed line is from the season six episode "Gossip." Though we never find out why Creed is so invested in this underwater diving technique, his earnestness makes us believe it.

Michael utters this line in the season five episode "The Duel." He's asked to come to corporate headquarters in New York City to explain the success of his branch to Dunder Mifflin CFO David Wallace.

This quote is from the season three episode "Branch Closing," in which it's revealed that the Stamford branch of Dunder Mifflin will be merging with the branch in Scranton. This is how Jim, Andy and Karen all end up working in the same office.

This line is from the season six episode, "Koi Pond," which premiered on October 29, 2009. When it first aired, the episode featured a scene in which Michael turned the warehouse into a haunted house for kids. The scene has since been removed, as it was found to be too upsetting — Michael "pranked" the kids by pretending to hang himself.

Andy says this in the season nine episode "Finale," which is indeed the last episode of the series. He's feeling nostalgic after being reunited with the old office gang to watch the screening of the documentary about the former Dunder Mifflin employees.

This oft-quoted Michael Scott line is from the season two episode "The Fight," in which Michael and Dwight have an unorthodox battle at a dojo. Michael wins, but not because he played fair.

In the episode titled "The Convict," which aired during the third season of the show, Michael makes this comment as "Prison Mike," one of his many unintentionally ridiculous characters. Of course, Dementors are from a very different entertainment franchise.

Ryan resorts to this technique after Michael had a painful accident in the season two episode "The Injury." What was the injury, you ask? Something only Michael Scott would do — he burned his foot on a George Foreman grill.

The character of Gabe did not make his first appearance on the show until the season six episode "Sabre." He dressed as Lady Gaga in a season seven episode called "Costume Contest."

Kelly makes this comment about herself in the season seven episode "Counseling." Unfortunately for all of the workers who sit near her in the office's back annex, they have to do the same.

Unfortunately, a batch of paper with an impolite watermark has been distributed, so Dunder Mifflin must go into damage control mode. Kelly makes her statement when she's tasked with training the office accountants, Oscar, Kevin and Angela, to be customer service reps in the season three episode "Product Recall."

Creed shares this funny (and incorrect) fact in the season three episode "Grief Counseling." He also claims that Ed Truck, Michael's former boss, got his head chopped off in a car accident, though in all likelihood this is not true.
