Quotes from 'Much ado about Nothing'

Who is the speaker of these quotes and what dramatic significance do they have, as well as what do they mean?

1) "The savage bull may, but if ever the sensible Benedick bear it, pluck off the bull's horns and set them in my forehead, and let me be vilely painted, and in such great letters as they write, here is good horse to hire: let them signify under my sign, here you may see Benedick the married man."
This quote was spoken by Benedick and seems to mean that Benedick is trying to say that is he is ever domesticated it is best that you put the bull's horns on his forehead and instead of putting a sign on his neck saying "Horse for hire" it will say, " Take a look at Benedick, the married man."
The significance of this quote seems to be the fact that it is making the plot clearer and adding interest to the play. This interest to the play is made by the way in which Benedick is convinced that he will NOT get married to anyone and finds that if he was ever to do such a thing it would be best if someone just put a sign on him and made it known to the world.


2) " What should I do with him- dress him in my apparel and make him my waiting gentlewoman? He that hath a beard,is more than a youth : and he that hath no beard, is less than a man: and he that is more than a youth, is not for me, and he that is less than a man, I am not for him, therefore I will even take sixpence in earnest of the Berrord, and lead his apes into hell."
This quote was spoken by none other than Beatrice, and seems to mean that Beatrice doesn't want a man who does not have a beard for he will seem like a lady, and is he has a beard he would be more than a boy which means that he is not for her. If he does not have a beard on the other hand, then he would be less than a man, making her not for him. The rest of the quote means that people say that women who do not marry will go to hell, and Beatrice understands this and believes that it will be her fate to be destined to hell since she will not marry.
The dramatic significance of this quote is to further enhance the plot of the play by showing the audience that Beatrice, like Benedick, is skeptical and refuses to get married, or well seems to believe that they will not get married. As far as Beatrice is concerned, she is not for any man and no man is for her.
