This week on Randling, is it a paint colour or is it a porn star? The Northern Thrusters and Roget's Ramjets - Wendy Harmer, Benjamin Law, Robyn Butler and Rob Carlton - contemplate whether the hottest Ginger of all was on Gilligan's Island, and why 'adult movie' scripts only seem to have vowel sounds. Other moments to look out for include: Wendy auditioning for series two of The Voice, Rob and Robyn adding another chapter to the history of rap, and a soft drink that guarantees 10,000 milligrams of pig placenta in every bottle.
