It was all fun and games with typical Jim Halpert's pranks on Andy Bernard (Ed Helms)...until he punched a hole through the wall.
"Cornell, ever heard of it?"
Andy was extremely proud that he went to Cornell, a fact that Dwight Schrute (Rainn Wilson) exploited to get under his skin in an interview that culminated with the two yelling and pushing one another across a desk.
Andy was pretty proud of his acapella skills—using them to win over Angela at one point—and felt that Pam (Jenna Fisher) and Jim (John Krasinski) may even want them to play at their wedding.
When the couple wasn't convinced, he put on a show in the break room to try to change their minds.
Andy finally got promoted to being branch manager, and one of his first moves was to make billboards to advertise their new low prices.
Unfortunately, as Jim pointed out, they all seemed to be him with an invisibly phallic object, and eventually we saw graffiti artists add in some inappropriate imagery.
Every character on The Office has a moment that is hardest to watch—Michael with his Scott's Tots philanthropy or Jan dancing during "The Dinner Party"—and Andy's may be when he accidentally ruins his play.
After getting everyone in his office excited to go see the local community's rendition of Sweeney Todd, Andy's phone goes off during the performance, and he goes off-script to awkward but hilarious results.
When Dwight and Andy both go for Erin (Ellie Kemper), they get into a pretty intense duel with their instruments that's a joy to see.
For everyone but Toby, that is.
It wasn't a match between Andy and Pam, but that may be Jim's fault.
After Andy tells Jim that he's interested in Pam, Jim gives Andy advice on how to win Pam over that is secretly all of her least favorite things, including playing a banjo and singing falsetto.
Andy learns that Angela is cheating on him and challenges Dwight to a duel.
Despite all of the weapons he has around the office, Dwight is no match for Andy's silent Prius car that sneaks up on him and pins him to a wall.
Ultimately, Andy realizes he deserves better.
When Michael (Steve Carell) announces he will be going to corporate, he uses a beach day to find his replacement.
Andy wears a sumo costume to battle it out for some points, but accidentally falls into a river and floats off into the night.
The biggest trend of 2004 was none other than parkour and Andy, Michael and Dwight use the office as their own crash course.
Rabies is the silent killer, but so is running so hard your nipples start to bleed.
Unfortunately for Andy, despite all his prep, he still found himself bloodied and bruised after the fun run to end rabies.
Andy proved his worth to the office workers by getting a tattoo that they designed to look like a baby nard dog, his iconic nickname.
Of course, he also decides to get this right on his butt.
