I didn't get this in the cartoon when it came up, and I still don't get it.

So people from rome are thought of speaking badly? I get that he speaks fast and it's hard to understand and whatnot, but how is it that the capital's accent is thought of as the worst? What's the more acceptable accent that you hear on the news based on?

EDIT : Or is it a specific accent within rome that he has, like Cockney?
