In Pass The Butterworms Cahill takes us to the steppes of Mongolia, where he spends weeks on horseback alongside the descendants of Genghis Khan & masters the ' Mongolian death trot'; to the North Pole, where he goes for a pleasure dip in 36-degree water; to Irian Jaya New Guinea, where he spends a companionable evening with members of one of the last head-hunting tribes. Whether observing family values among the Stone Age Dani people, or sampling delicacies like sautéed sago beetle & premasticated manioc beer, Cahill is a fount of arcane information & a master of self-deprecating humour.
