Ecce quam bonum et quam jucundum habitare fratres in unum! How great it is for brothers to dwell in unity! As we begin Part III, Murr and Kreisler each join different sorts of brotherhoods. Murr joins a cat fraternity, and Kreisler joins a monastery.

Meanwhile, Hayley and Pratima talk about their own failed attempts to participate in Greek life, and Nox has found a quiz to determine if Pebbles is a dreadful Philistine cat.

This very special episode features the titular song Ecce Quam Bonum (00:31:18), as sung by Murr and the other cats in the cat fraternity.
