In this episode, Sam and Chris are joined by the linchpin of their ever expanding podcast network, Mario D'Agostino. Coming at the end of a mammoth podcast recording weekend, the guys discuss space and toothbrushes, exploring pulsars both celestial and dental. Elsewhere, Chris attempts a religious ritual and brings a song promoting the avoidance of untimely death while Sam gets us all lathered and excited about a new quiz. Throughout the episode attempts are made to keep Mario on a short leash so that he doesn't go overboard with a particular hyperintrajocularity, but these attempts, for the most part, utterly fail.
