Extremophiles!
b'Our animal episodes seem popular, so episode 9 is a return to silly beasties -- in this case Sean and Nathan are talking about organisms that like to live in EXTREME environments, organisms called extremophiles.Sean and Nathan discuss the plural of octopus, with Sean starting out wrong with octopi (wrong!), Nathan offering octopussies (hmm) then switching to octopuses (best accepted answer).
