Much Ado about Nothing, and Twelfth Night.
In one of this man's works, The King of Navarre and his three friends vow to focus on their studies instead of on women. Balthasar sings "Hey nonny, nonny" for Don Pedro, and Borachio makes Claudio believe that Hero is unfaithful to him in a work by this author, who created the slow-witted Sir Andrew Aguecheek in a play in which Olivia falls in love with Cesario, who is really Viola in disguise. For 10 points, name this Elizabethan playwright of Love's Labour's Lost, Much Ado about Nothing, and Twelfth Night.
