It is a playful science documentary that follows intrepid host Anthony Morgan as he explores the wild world of the anus. Yeah, we know. From a beetle that can use its rear end as a weapon to an invertebrate whose butt is located in its gills, from a Norwegian vessel studying marine invertebrate bums to our collective cultural obsession with the human tush, and from an exam room during a routine colonoscopy to a Japanese lab working at the cutting edge of medical research... "Butt Seriously" offers a cheeky global journey to the bottom of the bottom.
