Just like humans, most animals have to fart. Some use their gas as a warning to predators, while others use it to dive in the water. And beware, there is a real-life killer fart out there. It gives a whole new meaning to silent but deadly. With help from zoologists Dani Raibiotti and Nick Caruso, who have compiled the "Does it Fart" database, we'll explore the hows, whys and why-nots of animal farts. And we've got a brand new song from Lucky Diaz and the Family Jam Band all about, you guessed it, animal farts. This episode is truly a gas!
