This episode opens with a crime in Australia, and then takes us to South America to learn about the amazing pygmy marmoset.
What is the difference between a monkey and a primate? What defines a species? Do pygmy marmosets always have twins? What is a fingerling? Do pygmy marmosets fart when you touch their heads, and do they lick pee?
This episode also ends in Australia: Macken finally gets around to reading the Australian 5-star reviews.
