Homicidal Earth Burps and Murderous Sky Rocks: All About Extinctions

Asteroids, volcanoes, and sex lakes - in this episode we discuss the varied and sometimes hilarious hypotheses of why animals have gone extinct.

Toxic shock syndrome, menstruation, caterpillars, cursing. Extinctions of the past, with very little about our present. Brief discussion of a serial killer living on your street as a metaphor. Referring to non-avian dinosaurs as just dinosaurs. One brief joke about preferring suicide to talking about geochronology.
