Other than his ex-wife and despite appearances with a series of cultivated blondes, Edward de Bono has never publicly aligned himself with a woman. 'I'm looking for a fat, cross-eyed hunchback,' he explains, stifling a giggle. 'A prosthetic hump would do.' His delight evaporates when asked about his three grandchildren. 'Am I a doting grandfather?' He pauses. 'I'm a ... something grandfather, yes.' The fact that De Bono remains unperturbed by this lack betrays an emotionally austere childhood, and his passions for play, toys, and bad jokes tell of the same deprivation.
