Darren catches Joe hitting the sun beds, and we discover this is a part of a whole new approach to Joe's grooming. We hear about the potential for circuses in the Gaeltacht, and that leads us down a  rabbit hole trying to understand the widespread fear of clowns, and a sinister viral trend that made clowns so hated they had to retire Ronald McDonald. Some questions about the ocean lead us to a difference of opinion over some big claims about disappeared civilisations, and we end up hearing about zombie viruses rising from the thawing soil in deepest Siberia. And we, at last, decide to figure out if a real-life Death Star could be constructed.
