One day Jesus comes across an angry, stone-clenching, mob encircling a screaming woman. 'What's going on?' he demands. 'She's an adulteress,' cries a voice. 'She must be stoned to death.'

'Let he who is without sin cast the first stone,' replies Jesus, staring back at the crowd. At this, they fall silent, then one by one they drop their stones and shuffle off, ashamed. Except for one little old woman who staggers up to the adulteress with a monster of a rock in her arms. She raises it above her head and smashes it down on the other woman, killing her instantly. Jesus lets out a huge sigh then says, 'You know, Mum, sometimes you really piss me off.'
