Banquo's Ghost

As Macbeth returns back to his guests, he does't see an empty seat reserved for him. One of his guests assures him that his own seat is empty. When Macbeth finally looks around, he sees Banquo's ghost in his seat. He is startled and begins to talk to himself, saying he didn't do it. Lady Macbeth covers for her husband, exclaiming that this happens occasionally. She diagnoses this as a brief fit. Unfortunately Macbeth continues to talk and shout while pointing at his seat (Banquo's ghost).  He begs his wife to see what he sees but Lady Macbeth shouts back at him to turn his attention back to his guests. Macbeth puts himself back together but it's not long before he sees Banquo's ghost again in his seat. He plays this off by proposing a toast to his guests and to Banquo. Banquo's ghost stays; Macbeth gets annoyed and orders the ghost to go back to its grave. Banquo's ghost vanishes and Macbeth announces he is a man
once again.
