The Office is the gift that keeps on giving. Though the workplace comedy, which ran on NBC between 2005 and 2013, is celebrating its 15th anniversary this year, the series has remained extremely relevant today—and fans love that they can watch all nine seasons of the Scranton, Pennsylvania-based series on Netflix (until the end of this year, at least).

Since the show is still so well-loved, fans remain steadfast in their scrutiny of the main characters, as evidenced by the many fan theories that have popped up in the wake of The Office's series finale. One of the more intriguing theories revolves around accountant Kevin Malone, whose oddness is one of the things that makes him so likable. But was Malone as simple-minded as he seemed to be? According to one fan theory coming from Screen Rant, the answer is no. In fact, it proposes that Malone possesses one of the world's greatest minds.

One clue that makes this seem plausible occurs during the "Casino Night" episode, when Kevin shares that he won a World Series of Poker bracelet in the $2500 No-Limit Deuce-Seven Draw in 2002—a game that requires rare concentration, skill, and planning. Kevin has also been shown to be a schemer who thinks on his feet. For instance, he was the first Dunder Mifflin employee to figure out that Jim and Pam were dating, and he fooled Andy and Daryl during a game of Dallas so that he could leave with the cash prize. Perhaps he was concealing his genius the whole time as part of a long con to keep his colleagues in the dark?

If you're looking for some new Dunder Mifflin content to read, a behind-the-scenes book about The Office is available to purchase here. If that's not enough, there are plenty of other fan theories about The Office—including one that details why Michael hates Toby so much.
