Rejoice, Dunder-Mifflinites! Today is Oscar Nunez’s birthday! Nunez is best known for his role as accountant Oscar Martinez during the nine-season run of NBC’s The Office. Nunez had the opportunity to flex his acting chops over the course of the series, helping to summon some of the series’ funniest and most cringe-worthy moments. In honor of Nunez’s big day, check out some of the actor’s highlights on the hit show.

Season 3, Episode 1: “Gay Witch Hunt”

When Dunder-Mifflin, Scranton, regional manager Michael Scott (Steve Carell) accidentally outs Oscar as a gay man, Michael makes things progressively worse by taking it upon himself to educate his employees about (his view of) gay culture. Michael’s obliviousness culminates in him trying to kiss a heavily disgusted, yet resigned, Oscar, creating a situation where you can’t help but stare at the uncomfortableness that permeates the room. Nunez plays the scene with equal parts frustration with Michael’s childishness and sympathy for his boss’ pure haplessness.

Season 6, Episode 10: “Murder”

When Michael attempts to distract his employees during a day when the future of Dunder-Mifflin is up for grabs with a murder mystery set in the south, Oscar instead uses his time to keep an eye on the behind-the-scenes business moves the paper company is making for some indication of which way the wind is blowing. When Oscar tries to alert his coworkers with updates, Michael insists the accountant speak in a southern accent, resulting in the worst and most chucklelicious attempt at a Georgian patois ever filmed.

Season 7, Episode 22: “Goodbye, Michael”

Michael is leaving Dunder-Mifflin to move to Colorado with his fiance Holly (Amy Ryan), and he uses his last day to say goodbye to his coworkers by bestowing them with gifts. As he tells Oscar, Michael considers the accountant his “scarecrow, because [Oscar] gave [Michael] a brain.” (You read correctly.) As such, he gives Oscar a horribly-made scarecrow doll, which, as Michael tells the documentary crew later, “looks like it was made by a two-year-old monkey.” The understated restraint Nunez portrays in attempting to show pride in Michael’s clearly awful work is a joy to behold.

Season 8, Episode 12: “Pool Party”

When new boss Robert California (James Spade) has a pool party at his mansion for a last hurrah before he sells it, Oscar takes the shindig as a rare opportunity to cut loose and embody “Bacchus, the god of wine.” Nunez’s barely-contained joy in this performance bursts through. If you don’t smile a little, you might be dead on the inside. (His bit starts at the 0:48 second mark.)

Season 9, Episodes 24/25: “Finale”

On the final episode of the series, Oscar is explaining to an employee why former fellow accountant Kevin (Brian Baumgartner) was fired. Oscar’s impersonation of his sometimes clueless coworker? Priceless.
