The McCarthys The McCarthys

It's one thing to master the Boston accent, but it's another to actually speak like a Bostonian.

What's up with time-jump bangs?

The cast of The McCarthys was up for the task though. In the exclusive video below, the stars of the new CBS sitcom — which follows a sports-crazed Southie family and its gay, sports-phobic golden child Ronny (Tyler Ritter) — test their knowledge of Boston slang... that is, if they even know what a grinder sandwich is in the first place. (Also, should Beantown's very own Joey McIntyre even be allowed to play?)
