Sir Andrew Aguecheek (also spelled Ague-cheek) is a comic character in William Shakespeare's play Twelfth Night, or What You Will. One of the main characters, Sir Andrew is a stereotypical fool, who is goaded into unwisely duelling with Cesario and who is slowly having his money pilfered by Sir Toby Belch. He is dim-witted, vain and clownish. His role in the play not only provides comedy through his pathetic situation and his long speech, but also by his distinct, long-faced appearance and garish dress sense. The role has been a favorite for noted actors such as Alec Guinness, Christopher Plummer, Paul Scofield and Roger Rees.
