There's always that one guy in your office who is so straight-laced, trying to stay out of the fray, but somehow always gets involved in the office antics. When it came to Dunder Mifflin's Scranton office, that person was Oscar Martinez. Played by Oscar Nuñez on the hit NBC series The Office, Oscar was the rational, intelligent, and often exasperated accountant. Always trying to be the voice of reason, Oscar had his moments of fun, but his character was so beloved because of the hilarity of his trying to maneuver his way out of the chaos.
