Act II, Scene I: Leonato says that Beatrice will never get a husband with such a "shrewd tongue" in Line 15. Why did he say this?

Beatrice is very witty and has a way of putting men in their place. Beatrice says that a combination between Don John and Benedick would create the perfect man, one who spoke just enough. Leonato tells Beatrice she will never get a husband if she continues to make such "shrewd" remarks. Beatrice acknowledges that she is happy without a husband and plans to die a spinster.
