Who the hell cares if this show is not historically correct? This isn't the History Channel, this is a comedy. I've seen far too many period pieces take themselves far too seriously. It's a genre well-trodden, but hardly ever done with wit like this.
If you can't see that this is the funniest show on television, your sense of humor must be broken.
