Quote from Kevin in Money
Andy: No, actually whomever is the formal version of the word. Oscar: Obviously, it's a real word, but I don't know when to use it correctly. Michael Scott: Not a native speaker. Kevin: I know what's right. But I'm not gonna say because you're all jerks who didn't come see my band last night. Ryan: Do you really know which one is correct? Kevin: I don't know.
