Why have you suffered me to be imprisoned,
Kept in a dark house, visited by the priest,
And made the most notorious geck and gull
That e’er invention played on? Tell me why.
– William Shakespeare
Twelfth Night, Act 5, Scene 1. Malvolio confronts Olivia over the writing of the love letter. He accuses her of doing him “notorious wrong,” having him imprisoned for mental illness and making him the biggest fool that ever had a joke played on him. Of course the letter is a lie and a forgery and he has been pranked.
