What does Sir Toby say to flatter Sir Andrew? Cesario/viola? What is Sir Andrew's response?

Please provide the scene for this otherwise I can't be completely sure where you are referring to. Sir Toby flatters and persuades Sir Andrew that he should challenge Cesario to a duel, and that, if Sir Andrew wins, he will surely gain Olivia's affections. Sir Toby tells him to write a letter of challenge, which Sir Toby will deliver; Toby actually has no intent of sponsoring a duel, but thinks the exercise might cool Sir Andrew off a little. Maria then enters, and begs them all to come see Malvolio, who is acting like a complete idiot in front of Olivia.
