Oscar Martinez is an accountant at Dunder Mifflin Scranton. He is a Latino of Mexican descent.

Michael: Should I bring a dictionary?
Oscar: The hospital will provide dictionaries. Bring a thesaurus.
Oscar: So, Pam told me you do a great Stanley impression. I'd love to hear it.
Jim: Oh, um. "Why do you keep CCing me on things that have nothing to do with me?"
Stanley: Is that supposed to be me?
Jim: Oh, hey, Stanley. Uh, I was just doing an impression.
Stanley: I do not think that is funny.
Pam: He does everyone in the office.
Stanley: Hmph. [leaves]
Jim and Pam: "I do not think that is funny."
