‘Taking liberties’ looks at the relationship between comedy and aggression. Does laughter embody or diffuse aggression? One theory states that the laugh may be an aborted cry of concern, or a way of announcing a false alarm. Another theory has it that chimp laughter is triggered by physical contact, or the threat of it, and argues that the laughter of a human evolved from the breathlessness of physical play. Ridicule and derision are both rooted in laughter. Comedy can be cruel. To ‘humour’ someone is a way of enjoying their charms whilst also seizing on their limitations.
