Luke’s Jesus tells funny stories. Humour has been found throughout Luke’s Gospel, and particularly in his parables. It is the contention of this article that the stories of the “lost” in Luke 15 are best understood as Jesus’s engaging in observational comedy, commenting upon the ridiculous behaviour of humankind. Working men, housewives, fathers, sons and brothers all show exaggerated attitudes and foolish actions. Everyone is invited to identify with them and laugh at them, but then to understand that, when it comes to sinners, God is just as foolish as us.
