Brian Baumgartner, Kevin
If the episode where Kevin drops his famous chili didn't give you secondhand embarrassment, it absolutely should have. Another member of the accounting department, Kevin's intelligence has been questioned on several occasions, Angela berating him about mistakes. Unfortunately, he's just not that bright and not that coordinated.
A Brand Deal
The aforementioned chili actually landed Baumgartner a deal with Bush's Baked Beans. He's also been featured in Hand of God, Good Behavior, Life in Pieces, and The Goldbergs. He's typecast himself thanks to his role as Kevin, but hey, it works.
